Venue: Tianjin Dongjiang Port Reclamation Project Site. The mud blower is constantly "spitting" the mud dug by the offshore dredger ashore; Bulldozers are leveling gravel and soil; The pile driver embeds the cement column in the depth; The workers are working nervously and orderly. ...
Five years later, the largest reclamation project in China will be completed here-33 square kilometers of artificial reclamation, forming a large container terminal area, logistics processing area and port supporting service area, with terminal loading and unloading warehousing, logistics processing and business office.
And other functions.
The construction of Dongjiang Port Area is just one of many large-scale construction projects in Tianjin Binhai New Area. Since Binhai New Area was incorporated into the national development strategy, it has ushered in a large-scale development and construction boom.
The rolling tide of construction contains unlimited business opportunities.
More than a dozen major projects have driven huge investments.
"After Binhai New Area was incorporated into the overall national development strategy, some long-declared major projects were approved by the state." Wang Kai, director of the Policy Research Office of Tianjin Binhai New Area Management Committee, said that the investment brought by these large-scale projects is unprecedented in Tianjin.
According to the introduction of Tianjin Development and Reform Commission, Tianjin has decided to focus on promoting the construction of about 30 major projects this year, most of which are projects in Binhai New Area, including several projects with investment exceeding 10 billion yuan. These 30 major projects include 10 projects that started years ago and need to be accelerated this year, 10 projects that are guaranteed to start this year, and 10 projects that are fully prepared in the early stage. The total investment of 30 projects is 299.5 billion yuan, and the investment completed this year is 34.4 billion yuan.
The total investment of 10 major projects that started in an all-round way this year is estimated to be 94.8 billion yuan, and the investment completed this year is11400 million yuan. These projects include 654.38+900 million tons ethylene project with a total investment of 2,654.38 billion yuan, road network project in the core area of Binhai New Area with a total investment of 654.38+965.438 billion yuan, infrastructure construction in the central business district of Binhai New Area with a total investment of 654.38+500 million yuan, and Beijiang Power Plant project with a total investment of 654.38+239 million yuan.
These large-scale projects not only have huge investment, but also will form an industrial agglomeration effect and drive related investment. For example, the one-million-ton ethylene project of Tianjin Petrochemical, which is about to start in June this year, will boost the industrial output value by hundreds of billions of yuan every year, promote the overall upgrading of Tianjin's traditional chemical industry, and form a world-class national petrochemical base, which has a strong industrial driving force and agglomeration effect on surrounding areas, and then drive related investments.
Infrastructure construction is the key, and 21800 million yuan will be invested this year.
The new round of development and construction of Tianjin Binhai New Area starts with infrastructure construction to enhance the function of urban carrier. This year, 80 key infrastructure projects will be arranged with a planned investment of 21800 million yuan.
Among the 80 infrastructure projects, this year will focus on promoting the construction in five aspects:
First, speed up the construction of urban expressway network. Through the construction of several urban expressways, the traffic links between Tanggu, Hangu and Dagang in Binhai New Area will be strengthened, and the traffic links between Tianjin central city and Binhai New Area will be strengthened at the same time.
The second is to speed up the construction of port-dredging railway and urban rail transit. Continue to build the South Xinjiang Port Entry Railway this year; Accelerate the second phase construction of Jinbin light rail; Start the construction of hub station in Beijing-Tianjin intercity railway new area; Construction of New Traffic Experimental Line Project (Light Rail) in Tianjin Development Zone.
The third is to start the construction of port-city traffic separation project. Focus on the viaduct in the middle section of Haibin Avenue and the overpass along the line, do a good job in the preliminary work such as fund raising, and strive to complete the survey and design in the first half of the year and formally start construction in the second half. Accelerate the construction of the second line of Beijing-Tianjin-Tangshan Expressway and connect with Haibin Avenue as soon as possible.
The fourth is to speed up the construction of municipal, public and energy facilities. Actively promote projects such as Beijiang Power Plant, Dagang Power Plant No.2 Station and 220 kV double-circuit power supply network. Start the construction of two water conveyance systems from Jinbin Waterworks to Kong Lin Industrial Zone and from Ninghe Yuelong to Tianjin Development Zone. Promote the seawater desalination projects of 654.38+10,000 tons in Tianjin Development Zone and Dagang District150,000 tons.
The fifth is to promote the construction of regional infrastructure in key development areas. This year, we will speed up the land requisition, demolition and land management in key development areas such as the West Zone of Tianjin Development Zone, Airport Processing Zone, Central Business District and Leisure Tourism Zone, and do a good job in the construction of municipal facilities such as roads, electricity, communications, water supply and drainage.
Pi, director of the Tianjin Binhai New Area Management Committee, said that speeding up infrastructure construction requires sufficient funds as a guarantee. On the one hand, Binhai New Area should undertake and make good use of bank loans, at the same time, it should innovate investment and financing ideas, expand the scope of attracting investment and raise construction funds through multiple channels.
Rich in land resources, real estate has become a hot spot for investment.
After Binhai New Area was incorporated into the national development strategy, local residents felt the most: there were more large-scale meetings, more construction sites, more people, more logistics, and more importantly, house prices went up again and again.
"Three years ago, the house price in Tanggu did not exceed 2,000 yuan/square meter, and it rose to about 4,000 yuan/square meter last year. Now, the average house price here has reached 5500 yuan/square meter. " Mr. Li, who has worked in a foreign company for five years, lamented the huge increase in house prices.
The former Binhai New Area, especially the development zone, was just a traditional industrial area with imperfect urban functions. Most workers working in the development zone live in the urban area, and there is always a long "bus queue" on the expressway connecting the urban area and the development zone during commuting hours. With the promotion of the strategic position of Binhai New Area, especially the positioning of Binhai New Area by the state, it is not only a manufacturing and R&D transformation base, a shipping and logistics center, but also an "ecological city". Therefore, the value of real estate development here has been rediscovered, real estate developers have taken a fancy to its commercial potential, and ordinary citizens also have the desire to live or invest here. The real estate market in Binhai New Area is unprecedentedly active.
According to incomplete statistics, there are currently more than 30 real estate projects for sale, under construction and about to start in Tanggu District and Binhai New Area Development Zone, with a total construction area of over 5 million square meters. Among these projects, the starting price of mid-range buildings ranges from 5200 yuan to 5600 yuan/square meter, and some high-end houses even reach 1. 1 000 yuan/square meter.
Rong, director of Tianjin Zhongyuan Real Estate Business Department, believes that the population growth rate of Binhai New Area, especially the development zone, will exceed 20% every year. If there are three people in each family, this growth rate will bring nearly 7,000 houses, as well as a series of needs such as shopping, office and leisure. With the further improvement of the infrastructure level and industrial upgrading in Binhai New Area, more migrants will also create a lot of demand for the development of the real estate industry.
In terms of land development cost, Tianjin Binhai New Area has 1.200 square kilometers of saline-alkali land, which is not suitable for farming and can only be used as ecological land and construction land, providing a broad resource platform for real estate development. It is understood that Tianjin will give priority to the planned land use index of Binhai New Area this year. According to the demand for construction land in the new area, the planned land use index of Binhai New Area reached 1.200 hectares in 2006, accounting for 34% of the total planning of the city, which was 4.3 times that of Binhai New Area in 2005. A large number of land resources have great temptation to real estate developers.
Land reclamation in the Pearl River Delta urban agglomeration makes the Pearl River Estuary narrow and prone to waterlogging.
May 2007 16 13: 43 Southern Newspaper Network-Southern Metropolis Daily Keywords: Pearl River Estuary
Guangzhou Wanqingsha 2 1 week survey: Experts believe that disorderly reclamation will easily lead to waterlogging and red tide.
Review of Land Reclamation in Pearl River Delta Urban Agglomeration (Phase VII)
The narrowing of the Pearl River Estuary is not only the change of the coastline on the map, but also the environmental harm it brings will affect our lives for a long time to come. The important reason for the narrowing of the Pearl River Estuary is the reclamation of land in the Pearl River Estuary urban agglomeration.
The Pearl River Estuary is the largest reclamation area in Guangdong. According to statistics, in recent years, the total area of land reclamation in Guangzhou, Dongguan, Shenzhen, Zhuhai and Zhongshan has reached 6666.7 hectares. Since 1963, although 1997 was suspended for a time, expert surveys show that Lingdingyang in the Pearl River Estuary is still shrinking after 1997, which shows that people have been going to sea for 40 years. According to reports, the water area of Lingdingyang has decreased by nearly110 compared with that before 1977.
When people cheered for the land reserve and almost immediate economic benefits brought by land reclamation, hidden dangers also appeared. Geological experts and water conservancy experts said that land reclamation blocked some natural spillway, which led to the rise of groundwater level and waterlogging; The self-purification ability of seawater is weakened, which leads to the deterioration of water quality and red tide.
"Some reclamation projects do not have much impact on the environment at present, but in a few years or decades, they may have irreparable effects."
-19965438+On February 24th, then Governor Lu Ruihua made a speech at the Guangdong Ocean Work Conference.
On April 30th, it was sunny. Wanqingsha Town, Nansha District, Guangzhou (Note: Wanqingsha Town originally belonged to Panyu District. On April 28th, 2005, the State Council approved the establishment of Nansha District, and Wanqingsha Town of Panyu District was transferred to Nansha District. Because the reclamation is before the zoning change, this paper still uses "Panyu" to refer to Jiuzhong Waterfront Wharf. A row of fishing boats marked "Walk with the Sea" docked on the shore.
Huazai is the owner of a fishing boat. Fishing boats used to be rented to urbanites to fish and eat at sea.
Hua Zai said that the change of their lifestyle was all due to land reclamation. Hanako supports this change. "At least, it has changed the previous dependence on the sea and changed the previous working method of' drying on the head and steaming under the feet'".
After reclamation, there are a lot fewer fish, and it is difficult to feed a family by fishing. Hua Zai said that in the past, there were at most 30 fishing boats accompanying the sea, but now there are only 14. Some boats were scrapped, and some went back to fishing.
Huazai's father, Uncle Gen, has lived in Wanqingsha for more than 30 years. He witnessed the whole process of land reclamation in Panyu in recent decades. He still remembers that from Sanyong, it was still a part of Wang Yang. At that time, the sea was rich in seafood, and every time I went out to sea, I got something, so I basically didn't have to worry about life. For decades, with the reclamation of land, the sea surface has become smaller and smaller, and the land has begun to rise from the sea surface, gradually forming a unique twenty-one enclosure. He said that there were many river worms that could be killed in those years, but now they can't be seen because of the reduction of sea area and serious pollution. "Now, if you go fishing, you have to pay for oil."
Fill the twenty-one circumference of wanqing sand.
Wanqingsha has 2 1 enclosures, of which 19 enclosures are located at the junction of Neilingdingyang and Guangzhou Pearl River Estuary. Twenty wai and twenty-one wai are two pieces of land extending to the sea from the nineteenth wai, which were formed around 1997.
Uncle Gen said that all the 21st districts are reclamation projects. In the words of the time, this is the result of human conquest of nature.
Sand gushing in the 21st century-the southernmost point of Guangzhou, before 1997, is the fastest and most reclaimed place in Guangdong. Now, when the reporter walked on the embankment paved with fine sea sand, there was no trace of the project at that time. Standing on the dam and looking out, you can clearly see Zhongshan on the other side. Panyu and Zhongshan meet constantly in important places in the sea. According to the introduction of the local elderly, the sea was very wide before the reclamation, and it was not easy to see Chu Zhongshan clearly. Later, both sides were surrounded by the sea and the distance was getting closer and closer. "At this rate, Panyu and Zhongshan will be connected in less than ten years."
Panyu district is located in the export waters of the Pearl River to the South China Sea. From north to south, it is a slightly trumpet-shaped estuary with a width of about 2.4 kilometers. Panyu is close to the four major estuaries of the Pearl River system-Jiaomen Waterway, Li Hongqi Waterway, Hengmen Waterway and Humen Waterway, which discharge 60% of the flood of the Pearl River system into the bay. According to the data, the sediment flowing downstream from the east, west and north rivers is constantly filling up, and the annual sedimentation rate is 2.4 cm. Over time, a vast beach has been formed here. There is a tidal flat area of 280,000 mu in Jiaomen reclamation area alone, of which 6.5438+0.3 million mu can be used for recent reclamation, and the water depth is more than 2 meters.
In this regard, the local people believe that "Panyu is blessed with land reclamation".
As early as 1963, Panyu established a reclamation company to be responsible for the reclamation and development of these beaches. Reclamation companies enclose these natural beaches, add dams and build irrigation systems, which can be used as farmland. 1970, the reclamation company organized the "reclamation conference battle" in Jiaomen reclamation area. It took two years to concentrate tens of thousands of migrant workers in the county to work in reclamation areas. By 1978, the cultivated land area has expanded by 1733 hectares. The maturity of tidal flat is along the direction of new reclamation and the extension of the 19 th flood. Generally, it takes about 3 years to fill a frame, which belongs to enclosure. There will be a river between every two paddocks for drainage and drainage irrigation. These rivers also correspond to the location of the fence and are named by numbers. For example, the river corresponding to enclosure 19 is named as article 19. During the period from 1984 to 1997 and 14, Panyu Reclamation Company reclaimed 89,800 mu (about 5,987 hectares), with an average annual rate of 6.9 1 1,000 mu (about 46 1 hectare).
In fact, Panyu can be said to be an area surrounded by the sea. According to the records of Guangzhou, 80% of its land comes from the sea.
Nowadays, times have changed. When reporters walk on this land that used to be the sea, there is no memory of the sea here. The reclaimed land is staggered by land and water, and you will be intoxicated by the charming pastoral scenery here. With the emergence of tourist attractions such as "10,000 mu sunflower garden", the rural cuisine in this area has gradually emerged, especially in Panyu. Aquaculture farmers here have opened restaurants to Tiantang, and tourists fish, pick vegetables, cook and help themselves all the way.
Mr. Zhao from Sichuan contracted a big fish pond in Wai. He said that in Panyu alone, hundreds of people rented land by the sea, some planted lotus roots and some planted bananas. They are all contracted land from Panyu Reclamation Company (now Nansha Reclamation Company).
The duty of the reclamation company is to organize the orderly development of Panyu beach according to the plan, that is, reclamation. According to the planning of the Ministry of Water Resources and the Pearl River Water Resources Commission, the jurisdiction of Panyu Reclamation Company is in the area of Wanqingsha and Longxue Island in old Panyu. However, after 1997 stopped reclamation, the reclamation company mainly helped Panyu district government to manage the land with a land area of over 654.38+10,000 mu, openly bid for the existing cultivated land and collect the land rent.
Director Luo of the land office of the reclamation company said that they mainly rented the land to farmers to grow cash crops and aquaculture. He told reporters that the cost of reclaiming an acre of land in those years was about 6,543,800 yuan. At present, they contract to more than 3,000 farmers at the annual price of 700 yuan. These farmers come from Sichuan, Guizhou, Hunan and other places, as well as some locals. They grow sugarcane, bananas, lotus roots, fish and shrimp on these closed lands, and some agricultural products are exported overseas.
According to reports, these areas can probably pay thousands of dollars per mu, and ponds can pay more. "Compared with the investment of more than 6.5438+0 million yuan per mu, it has brought benefits far higher than the investment." Director Luo defines the input-output ratio of reclamation in this way.
The mass production of agricultural and sideline products has brought a large number of people who come to buy specialty products and sightseeing. Every weekend or holiday, some urbanites post on the internet, looking for someone to accompany them to Panyu reclamation area to enjoy the pastoral scenery. The increase of floating population has brought prosperity to the local economy. Some locals told reporters that Wanqingsha also paid attention to the first, third, fifth, fourth and sixth markets before, but now this phenomenon has faded. "Now there is basically everything on the street. Of course, you don't have to buy what you want at a fixed time like before." Driving the market has gradually become a memory in people's hearts.
The agricultural economy and tourism economy gradually took shape around 2 1 century, from which we can see the economic benefits brought by reclamation to Guangzhou and the Pearl River Delta region.
Narrowing of the Pearl River Estuary leads to waterlogging
However, on the contrary, experts in ocean, geology, water conservancy and other fields have been calling for and warning the ecological impact of land reclamation, forcing us to face up to the environmental and ecological problems that we have long been unwilling to pay attention to or ignore.
There are seven cities around the Pearl River Estuary, followed by Guangzhou, Dongguan, Zhongshan, Zhuhai, Shenzhen, Hong Kong and Macau. With dense population, convenient transportation and developed economy, it is one of the most developed areas in China, and the Pearl River Estuary is also the most reclaimed area in Guangdong. According to the statistical results, the total area of land reclamation in Guangzhou, Dongguan, Shenzhen, Zhuhai, Zhongshan and other places in recent years has reached 6666.7 hectares, regardless of the engineering sea.
The land reclamation in these cities swallowed up the inland waters and narrowed the Pearl River Estuary.
During the period of 1996, a severe flood occurred in South China, which occurred once every 50 years in Wuzhou, the middle reaches of the Pearl River, and once every 200 years in Ying Ge Mouth, the lower reaches of Zhongshan. Yang Chaoqun, a senior geologist in Guangdong Province, said in an interview with the media at that time that reclamation led to siltation in the estuary and poor flood discharge. The successive floods in the Pearl River Delta in recent years are closely related to the siltation caused by land reclamation and the rise of river bed water level. Director Luo of the Land Office of Reclamation Company admitted in an interview with this reporter that when a group of experts conducted research at that time, some geological experts and water conservancy experts put forward similar views: reclamation of land from the sea hindered some natural spillway, which led to local rise of groundwater level, which led to waterlogging in cities above spillway, which in turn led to soft land and destruction of underground water system. Terrible is that the Pearl River Delta region is low-lying and the soft foundation is widely distributed. In fact, some experts released information after investigation, saying that in recent years, Guangzhou, Shenzhen and other places found that many building foundations were soaked or even cracked, and basements were flooded, which was related to the rise of groundwater level.
From the Longxue Bridge in Shiliuwei, Panyu, you can reach Nansha Port under construction. According to the plan, after the completion of Nansha Port in Longxue Island, a square equal to 10,000 hectares of sand will be expanded to the south, and the reclamation area is expected to reach 1.5 million mu. Director Luo said that the reclamation of Longxue Island was approved by the State Council, not at will.
The background of Director Luo's remarks is:1In May, 1996, the Guangdong Provincial Government promulgated the Regulations on the Administration of Sea Area Use in Guangdong Province, which stipulated that the land department should organize expert argumentation with the departments of marine, aquatic products and water conservancy, and then report it to the people's government at or above the county level for confirmation, and the marine administrative department at the same level should issue a sea area use certificate and pay the sea area use fee. Therefore, Panyu stopped reclamation at 1997. 199 10 The Ministry of Water Resources issued the Measures for the Regulation and Management of the Pearl River Estuary, demanding that the disorderly, excessive and unpaid reclamation be resolutely stopped. At the Guangdong Ocean Work Conference on February 24th, 65438, Lu Ruihua, then governor of Guangdong Province, pointed out that "some reclamation projects have little impact on the environment at present, but in a few years or decades, they may cause irreparable impact" and demanded that "all reclamation projects should be stopped first and started after strict argumentation".
Since 2003, Professor Xia Zhen of Guangzhou Marine Geological Survey has conducted a three-year survey on the marine geological environment in the coastal waters of the Pearl River Delta. This project was initiated by China Geological Survey.
According to Professor Xia Zhen's investigation, after 1997, the Lingdingyang in the Pearl River Estuary is still shrinking. Zhongshan, adjacent to Panyu, continues to surround the sea. From the satellite photos studied by Guangzhou Marine Geological Survey 1996 and 2003, it can be seen that the cross gate area of Zhongshan increased by 1/3 after 1996, and expanded into a huge rectangle in the direction of Li Hongqi waterway. That is to say, during the period of 1996-2003, the Hengmen of Zhongshan reached 6.3 kilometers into the sea at the farthest, and the largest piece of land reclaimed from the sea reached 8.6 square kilometers, most of which was used to grow cash crops such as bananas. Just like another Panyu.
Professor Xia Zhen said that in fact, many people, especially local government officials, are aware of the importance of the environment, but they can only sacrifice the environment on the premise of economic development. Not many people are willing to explore the road of coordinated development of the two, not to mention that they may not succeed and have a long way to go.
According to Professor Xia Zhen, in recent years, the scale of reclamation on the west bank of the Pearl River Estuary is stronger than that on the east bank of the Pearl River Estuary. Because in addition to engineering construction, Zhongshan and Panyu also have large-scale reclamation projects. Among them, the most changes in the west bank are Zhongshan Hengmen East-West, Panyu New Reclamation Jiuchong and Longxue Island. The land of Longxue Island in Panyu, Guangzhou extends as far as 7.2 kilometers into the sea, and the largest reclamation area reaches 18.3 square kilometers. The coastline of the newly reclaimed Jiuchong River extends as far as 2.85 kilometers.
Shenzhen Bay, located on the east coast, has the longest coastline of 1.4km, Shekou Bay is about 0.7 km, Dachan Bay is about 1.5km, and the northern part of Qi 'ao Island is about 0.8 km.
The tide of sea reclamation has gradually eroded the waters of the Pearl River Estuary, tightening the pockets of the inner Lingdingyang, making the sea water shallow, the navigation channel not as smooth as before, the navigation channel shrinking and the Lingdingyang shrinking.
Professor Li Pingtian, a researcher at Guangzhou Institute of Geography, Guangdong Academy of Sciences, who has made a special study on this, once told the media: Lingdingyang has shrunk and eventually disappeared, which is indisputable in the scientific community. Now the main research is how long it will disappear. At present, there are two opinions: 780 years and 100 years.
Ecological destruction and water quality deterioration
"At present, I still think that the advantages of Panyu reclamation outweigh the disadvantages." Director Luo said: "Panyu reclamation has a theoretical basis. First, the reclamation here has a long history; Secondly, according to the investigation report of the Pearl River Water Resources Commission, the four major estuaries of the Pearl River belong to weak tidal estuaries, and the speed at which the Pearl River water comes here is reduced, resulting in a large amount of sediment deposition. "Even if it is not enclosed, it will become land. "
"We reclaimed these beaches by excavating sediments in the middle of the river and reclaiming land in the estuary. Although this is land reclamation, from another perspective, it actually dredges the runoff and is conducive to the smooth flow of the Pearl River water. " Director Luo said this.
"We reclaimed land and reserved a lot of land resources for the government. According to Guangzhou's southern expansion strategy, Panyu and Nansha will be key areas for Guangzhou's future development, and such land reserves are very important. " Director Chen, Party and Government Office of Reclamation Company, concurrently serves as the general manager of Guangzhou Nansha Port Development and Construction Company. He believes that with the increasing population and the continuous expansion of urban construction to rural areas, coastal reclamation is almost inevitable.
His basis is that the government has recovered 30,000 mu of 10 million mu of land reclaimed from the sea in Panyu, and these 30,000 mu of land are now in the eyes of several large companies, and land consolidation and factory construction are under way.
However, looking back on the reclamation of Panyu in the past 40 years and looking at the development of Panyu now, it is obvious that the speed of Guangzhou's expansion to the south is not as fast as that of people's reclamation!
On the other hand, the excessive reclamation in the Pearl River Estuary is not worth the loss in the eyes of many experts. Take the flood as an example. After 65,438+0,996,5438+0 years, the water conservancy construction in Zhongshan City has reached 6,543.8+0.24 billion yuan, and the income from reclamation is far from enough to reinforce dikes.
In addition, land reclamation in other cities in the Pearl River Estuary of Guangdong Province is in a disorderly and excessive state, and many projects blindly and illegally reclaim land without scientific argumentation, environmental impact assessment report and declaration of sea area use certificate. This reclamation caused the Pearl River Estuary to shrink, the water level to rise, the navigation channel to become smaller, the tidal capacity to decline, and the ecological damage was serious.
Experts believe that the smaller the port is, the smaller the tidal range will be, so that the scouring capacity of the tide will be reduced and the tidal absorption in the port will be reduced. The self-purification ability of seawater is weakened, which leads to the deterioration of water quality and may cause red tide. Since 1990, there have been 22 recorded red tides in the whole province, which have caused great losses to local fishery production.
It should also be noted that Professor Xia Zhen's investigation found that there are a large number of shoals in the Pearl River Estuary, which often cause ships to run aground.
Surrounding the ocean has also destroyed the homes on which some marine life depends.
Director Luo of the Land Office of the Reclamation Company also admitted that reclamation will definitely bring some bad things. He said, for example, the problem of marine biodiversity in the past, after reclamation, the wetland area is getting less and less, and the biological species are getting less and less. Land reclamation has also led to the destruction of a large number of mangroves.
Fortunately, in Guangdong, people have gradually realized the ecological changes brought about by land reclamation, and governments at all levels have begun to consider the price to pay to the sea. For example, in June, 2004, 5438+065438+ 10, the Shenzhen Municipal Government issued a document requesting that the 16 reclamation area, including Shajing and Baoan, should be reclaimed strictly within the scope of examination and approval, and should not be reclaimed at will.
"The field around the sea is called the sea, and there is a sigh in the sea." In the Pearl River Delta, when many areas still have the impulse to go to sea, maybe we may set foot on Lingdingyang, a land without sea, leaving only a sigh.
Reclamation peak
The advantages outweigh the disadvantages.
□ The four estuaries of the Pearl River belong to weak tidal estuaries, and the speed at which the Pearl River water reaches here is reduced, resulting in a large amount of sediment deposition, which will turn into land even if it is not enclosed.
Reclaiming land from the sea has reserved a lot of land resources for the government.
the loss outweighs the gain
□ After Zhongshan City 199 1 year, the investment in water conservancy construction to resist floods has reached 124 billion yuan, and the income from reclamation is far from enough for the investment in strengthening dikes.
-Illegal reclamation has narrowed the Pearl River Estuary, raised the water level, narrowed the navigation channel, reduced the tidal capacity and caused serious ecological damage. The self-purification ability of seawater is weakened, which leads to the deterioration of water quality and red tide.
