A large number of water hyacinths in Suzhou River destroy the ecological environment of the river! What is the reason for the large number of water hyacinths in Suzhou River? The annual "Green Devil" invasion reappears in Shencheng. On the afternoon of the 6th 13: 30, some netizens broke the news that a large number of water hyacinths appeared in the waters near East China University of Political Science and Law in Suzhou Creek. The reporter stood along Guangfu West Road and looked at the river. The dense water hyacinths almost occupy half of the river, which seems to float down from the upstream, and are also mixed with a lot of garbage, such as beverage bottles, disposable tableware, foam plastic sheets and so on. Ms. Liu, who has lived nearby for many years, said that she had never seen so many water hyacinths floating on the Suzhou River. As of press time, these water hyacinths are drifting downstream along the Bund.

The reporter called the relevant person in charge of the Water Management Office of the Municipal Greening and City Appearance Administration to inquire about the cause of the outbreak of water hyacinth in this section, but was told that the department would not be able to organize personnel to rush to the scene for investigation until tomorrow. The specific reasons are not clear at present. "I also received the above notice in the afternoon. Now is the National Day holiday, and I can't go to the scene until early tomorrow morning. " The person also stressed that the interview must be approved by the leaders of the Municipal Greening and City Appearance Administration. The reporter paid attention to the call time, which was 4: 22 pm, and it was not yet time for the staff on duty to get off work.

The reporter then called the water affairs and environmental protection departments. The other personnel on duty all said that at present, the management of water hyacinth mainly depends on salvage, and the municipal greening and city appearance administration bears the main responsibility. In case of emergency, we should organize forces to deal with it. As of press time, no department can give the preliminary investigation results in time, and it has not been disposed of in time and effectively.

It is worth noting that just two weeks ago, the Water Management Office of the Municipal Greening and City Appearance Administration also announced that the water hyacinth pollution in this city will not break out in a large area in the short term, and early warning and monitoring will be further strengthened to keep abreast of the growth and pollution dynamics of water hyacinth, and do a good job in ensuring the city appearance of the waters directly under the Huangpu River and Suzhou River during the National Day.

An insider of a salvage company in Shanghai told reporters that every autumn, Shanghai generally enters a large-scale outbreak period of seasonal aquatic plants such as water hyacinths, which seriously threatens the health of the river water environment in Shanghai. However, by the end of September this year, although a small number of water hyacinths had gathered at the interception points in the upper reaches of Suzhou Creek, such as Huacao, Jiande Garden and Zhoujiaqiao, the daily production could be ensured by combining labor and machinery. At that time, it was not expected that there would be a large-scale outbreak in the short term. As for the large area of water hyacinth in the waters near East China University of Political Science and Law, it may be related to the diversion of water from the sluice on June 3 10, which caused the water hyacinth in the tributary to drift down, and some employees of the salvage company had a National Day holiday.

According to the data, there was a rare peak of water hyacinth in Shanghai last year. From125 to the end of 10, the municipal greening management department salvaged 4,000 tons of water hyacinth every day. Insiders pointed out that this is related to the warm climate last autumn. 165438+1late October, the highest temperature still exceeded 20℃, which kept the vigorous growth of water hyacinth. In the month of 65438+February, the temperature plummeted, and a large number of water hyacinths withered and floated on the water surface mixed with domestic garbage, which was even more disappointing.
