What's the matter that the surrounding area of Erhai Lake is designated as an ecological protection area?

The Information Office of Dali Prefecture Government held a press conference, at which two government documents were released, one was the delineation and standardized management of the core area of the water ecological protection zone in Erhai Lake Basin, and the other was the Notice of Dali Municipal People's Government on the special rectification of catering inn service industry in the core area of the water ecological protection zone in Erhai Lake Basin.

In the Announcement on Delineation of the Core Area of Erhai Lake Basin, the core area of Erhai Lake Basin Water Ecological Protection Area is Haixi, Haibei (Shangguan Town)1.966m, boundary pillar100m, and the lakeside and off-road shoulder of the northeast area of Erhai Lake (Haidong Town, Caise Town and Shuanglang Town) is 30m, and Erhai Lake mainly enters.

The "Notice" clarifies that it is forbidden to build new buildings and structures other than environmental protection facilities and public infrastructure in the core area of the Erhai River Basin Water Ecological Protection Zone, and investigate and deal with illegal buildings and structures according to law; In accordance with the principle of "total control, only reduction without increase", the examination and approval of restaurants, inns and other business premises will be suspended, and the existing catering and inn service industries will be rectified and standardized; Large-scale breeding of livestock and poultry is prohibited.

The Dali government said that in recent years, with the improvement of Dali's popularity and reputation, the number of migrants has been increasing, and the catering inn service industry has developed rapidly. However, the investment in the construction of pollution interception and control facilities in Erhai Lake Basin is insufficient, the coverage rate of pipe network and sewage collection and treatment rate are low, and the debt is large, so the speed of pollution control cannot keep up with the speed of pollution increase. At the same time, affected by agricultural non-point source pollution and production and domestic sewage, the water quality of the main rivers entering the lake is poor, the amount of fresh water entering the lake is greatly reduced, and the water cycle is reversed. The water quality of Erhai Lake has been at the "turning point" from moderate nutrition to eutrophication, which is suitable for algae growth. Once the climatic conditions are met, the risk of cyanobacteria outbreak is greater.

According to the national water special survey, the total discharge of pollution load in Erhai Lake basin in 20 16 years increased by more than 50% compared with 2004. Livestock and poultry breeding, agricultural non-point sources, rural life and urban life (including catering inn service industry) are the main pollution sources in Erhai Lake Basin, among which the pollution brought by catering inn service industry is the fastest growing.

Erhai Lake is the second largest freshwater lake in Yunnan Province after Dianchi Lake. It is located in Dali City, Dali Bai Autonomous Prefecture, Yunnan Province, and is named after its human ear. The Dali Prefecture Government has decided to designate the core areas of the Erhai Lake Basin Water Ecological Protection Zone as the west of Erhai Lake, the boundary pillar extension of Haibei (Shangguan Town)1.966m, the extension of the lakeside and road shoulder in the northeast of Erhai Lake (Haidong Town, Wase Town and Shuanglang Town) 30m, the main rivers entering Erhai Lake and other parts of Erhai Lake Basin.

The rectification contents are: from April 1 day to April 10, and all catering and inn operators within the rectification scope are closed for inspection. For catering and inn operators who have not closed down within the time limit, the relevant functional departments shall investigate and deal with them according to law and suspend business for rectification.

Hotels and restaurants with incomplete licenses in the core area will be closed from April 20 17 1 day until the sewage interception project around Dali City is put into use. According to the official introduction, the sewage interception project may be put into use in June 20 18 at the earliest one year later.
