Jimu Journalists have called for many times the National Reserve Management Bureau of Hulun Lake in Inner Mongolia, and no one has answered the phone.

Jimu reporters noticed that on the evening of July 23, the official WeChat public account of the Publicity Department of the Hulunbuir Municipal Party Committee "Hulunbuir Release" released the "Hulun Lake Bascalty Water Huada Phenomenon gradually relieved". It is reported that "every year from the high temperature season every year, tourists who come to Hulun Lake often find such a phenomenon: the water body in the local lake area is greener and accompanied by a pungent smell. People in the lake area call it '' ' Moss is a natural ecological phenomenon. "Dou Huashan, deputy director of the National Nature Reserve Management Bureau of Hulun Lake in Inner Mongolia, introduced that" moss "is called" water ", which appears and low in water in the water body. It is a characteristic of the rich and nutritious water body. At present, the water body of Hulun Lake is in a moderate rich nutritional state.

Li Renhui, former director of the algae center of the Institute of Aquatic Biological Research Institute of the Chinese Academy of Sciences, confirmed to Jimu Journalist that the lake in the video was caused by cyanobacteria, which shows that the water body is rich in nutritional. In the 1990s, the lake appeared in the lake. At that time, he went to the scene for inspection.

Zhou Qiong, a professor at the School of Aquatic Products of Huazhong Agricultural University, introduced that the lake turns green and the formation of dense water in the video is caused by cyanobacteria. The richness of the water body is the main reason for the outbreak of the lake cyanobacteria. The nitrogen phosphorus in the lake water exceeds the threshold of rich nutrition. Under the blessing of factors such as temperature and wind, it has led to the emergence of water. In order to control the water of the cyanosal, the source of pollution in the lake must be controlled, and the filtering fish such as crickets and crickets should be applied to the amount of cyanosais that controls too much, and the number of aquatic plants in the lake is restored to prevent water reappearance by comprehensive governance.
