The west slope is gentle and inclined, and gradually expands westward into the central plain with little rainfall and drought for many years, showing a scene of grassland short irrigation. The great watershed runs from north to south and runs through eastern Australia. Its northern part belongs to tropical climate zone, its central part belongs to subtropical climate zone and its southern part belongs to temperate climate zone.
The eastern slope of the mountain range is steep, with abundant precipitation and humid climate; The west slope is gentle, in the leeward position and the climate is dry. It is the watershed between the Pacific water system and the Indian Ocean water system in the Australian mainland, with a tropical climate zone in the north, a subtropical climate zone in the middle and a temperate climate zone in the south. This long mountain system is like a natural barrier, blocking the warm and humid air from the Pacific Ocean, making the precipitation on the east and west slopes of the mountain very different, and the growing plants are also very different. Dongpo has steep terrain, long and narrow coastal plains, abundant precipitation and diverse forest types.
Climate Tropical desert climate is distributed near the Tropic of Capricorn from the mainland to the west coast. Like all tropical deserts, the cause of formation is controlled by subtropical high all the year round, and the cold current along the coast of Western Australia can reduce humidity. Savanna is distributed in the periphery of tropical desert because it is controlled by equatorial low pressure zone in summer and subtropical high pressure in winter. Merida-Ling Basin is the main mixed agricultural area in Australia, and a decent city is Darwin in the northwest corner.
The tropical rain forest climate is distributed in the northeast section of the Great Watershed, which is controlled by the equatorial low pressure all the year round, with high temperature and rain, and the warm current in East Australia warms up and humidifies, along the Great Barrier Reef.
The Mediterranean climate is distributed in the southwest corner and southeast corner, controlled by subtropical high in summer and westerlies in winter. The small distribution area is the reason for the lack of land.
The subtropical humid climate (which can also be simply considered as subtropical monsoon) is distributed in the Middle East, which is a great watershed.
Temperate maritime climate, distributed in the southeast section of the great watershed, extends to Tasmania, and is influenced by the warming and humidification of the westerly belt and the warm current in eastern Australia.
Generally speaking, the climate zone is semi-circular. The subtropical humid climate (Brisbane, Sydney, Canberra) to the east of the Great Divide, the temperate maritime climate (Melbourne, Hobart), and the Mediterranean climate in the southeast (Adelaide) and southwest (Perth) are more suitable, which is also the area where Australia's population and industry are concentrated.
The eastern coastal cities are located on the windward slope of the great watershed, with more precipitation and humid climate.
The great watershed in eastern Australia blocks the water vapor infiltration in the Pacific Ocean, so the climate in central Australia is affected by the ocean, which is greatly affected by being close to the ocean and less affected by living in the inland.
There is an Australian cold current flowing in the west, so the climate in the west is drier than that in the east, and the precipitation is less than that in the east.
Problems in Agricultural Production in Murray-Darling Basin, Australia
(1) Question: The shortage of irrigation water sources has become a restrictive condition for the development of agriculture and animal husbandry here.
(2) Reason: Basin A is located in the rain shadow area with little precipitation. The water quantity in Dalin basin varies greatly with the seasons. (The river swells in rainy season, and the big tributaries are often cut off in dry season. Although there is no cut-off in murray river, the river is very shallow in dry season, and some upstream areas will dry up in the driest year. C groundwater is rich but highly mineralized, which is not suitable for agricultural irrigation.
(3) Measures to solve it; East-to-west water diversion.
Rain shadow effect Rain shadow effect: Mountains can block the monsoon and form rain shadow effect. The precipitation on windward slope increases, but the precipitation on leeward slope is less. The typical representative of rain shadow effect is the different precipitation on the east and west sides of the great watershed in Australia. To the east of the great watershed are Sydney and Melbourne, where the climate is humid and pleasant and the precipitation is heavy. The west is an Australian desert, so the precipitation here is not high. Of course, this is also influenced by ocean currents.
The East-to-West Water Diversion Project has a great watershed from north to south in eastern Australia (generally 800~ 1000 meters above sea level), and Murray-Darling Basin is located in the west of the great watershed. Humid air from the eastern ocean brings abundant topographic precipitation on the east side of the great watershed. On the west side of the great watershed, the airflow sinks and the rainfall is scarce. The Murray-Darling basin is located on the leeward slope of the great watershed, so it is relatively dry. To this end, Australia spares no effort to build water conservancy projects, build reservoirs on the Xueshan River and its tributaries, and pass through tunnels or open channels by gravity or pumping water. He Xue River flows southward into tasman sea and into Murray-Darling Basin. This is Australia's world-famous Snow River water transfer project. Water transfer has produced great economic benefits: first, it has greatly promoted the development of agriculture and animal husbandry in Murray-Darling Basin; Secondly, it has produced huge power generation benefits, and the electric energy is transmitted to important cities such as Canberra and Sydney; Third, 16 large and small reservoirs built for water transfer are dotted among green trees and snow-capped mountains to form a tourist attraction; Fourth, the water quality in the west has been greatly improved and the ecological environment is pleasant.
Victoria, a neighboring state, is located in the south of Australia. Melbourne, the capital, is the capital and largest city of Victoria, the second largest city in Australia and one of the most famous cities in the world. After the administrative reorganization, the population of Mexico City itself is 52 1 17, most of the citizens live around the central business district, and the metropolitan population is 38 10/0,000 (June 2007). Melbourne has been rated as one of the top ten cities most suitable for human habitation by the United Nations and the best city in the world in 2005. The motto of our city is "Viresacquiriteundo", which means "go with the flow". From 190 1 to 1927, Melbourne is the capital of Australia. 1927, the federal capital moved to Canberra. Melbourne has successfully hosted the 1956 Summer Olympic Games and the 2006 Commonwealth Games.
Melbourne is the economic, financial, commercial and shopping center city of Australia and the southern hemisphere, and also the cultural center of the southern hemisphere.
Queensland Queensland, located in the northeast of Australia, is the second largest state in Australia, with Brisbane as its capital. The whole state covers an area of 6.5438+0.73 million square kilometers, accounting for 654.38+0/4 of Australia's total area. Two-thirds of the west is plain, and 1/3 of the east is hilly or mountainous. The great watershed runs through the whole state. Because the tropic of Capricorn of the earth passes through the central part of Queensland, Queensland has a sunny and warm climate, so it has won the reputation of the Sunshine State. Especially on the east coast of Queensland near the South Pacific Ocean, the sunshine is particularly abundant and brilliant, shining on the golden beaches and blue seas along the long coastline, as well as the colored corals in the transparent seawater. It is a wonderful paradise.
Queensland attracts many tourists with its blue waters on the Gold Coast, exquisite white beaches, the world-famous Great Barrier Reef and the tropical rain forest in the north. Warm climate, natural scenery and diverse activities-cruising, diving, surfing, fishing, whitewater rafting, skydiving, hot air balloon launch, four-wheel drive motorcycle, horseback riding, etc. -Let different people have fun in Queensland.
Queensland is rich in natural resources, with excellent subtropical climate and diverse natural environment. There are many rainforests on the east coast, with eucalyptus forest, Australia's national tree, and acacia forest, Australia's national flower, in the west. There are many kinds of animals, and you can see two rare egg-laying mammals, the echidna and the platypus. Therefore, eco-tourism is also one of the characteristics of Queensland.
Canberra, the capital of Australia, is a young city. With a total population of 325,000 (2004), it ranks eighth in Australia. The total area is 2395km?
