　　Since the beginning of winter, Datong Lake, which is 124,000 mu "the first lake in Sanxiang", has successively welcomed more than 100,000 migratory birds, presenting a scene of tens of thousands of birds flying together.

In the deep waters of the Great Lakes, Li Yangchang, a postdoctoral fellow from Wuhan University, worked with the workers to plant submerged plants such as salamander and bitter grass in designated areas.

　　"The water quality of the Great Lake has recovered by 70% to 80% in the past four years. Now it is mainly to build a multi-level underwater ecosystem in key waters and continue to improve it. This process is relatively long." It is Li Yang who settled in Liangzi of Wuhan University to make the lake reappear with clear waves. The goal and vision of the Datong Lake Workstation of the National Field Scientific Observation and Research Station of Lake Ecosystems.

　　Datong Lake is one of the four larger lakes that make up Dongting Lake. The water quality of Datong Lake was reduced to inferior V due to predatory farming by contracted enterprises.

Since the comprehensive management was launched in 2018, the water quality has continued to improve, reaching the IV standard in general. The vegetation belts and emergent plants along the lake have been basically restored, and wild mussels, shrimps, soft-shelled turtles and other previously disappeared species have reappeared.

　　The governance of Datong Lake is only a microcosm of "protecting a river and clear water".

From rectifying "severe diseases" to building an "ecological barrier", Hunan, where the "Longyao" of the Yangtze River is located, is continuing to manage the "Xiang, Zi, Yuan and Li" waters by linking Dongting Lake and the "Kidney of the Yangtze River". "Raise a new face and flow out a river of clear water.

　　"In recent years, Hunan has always taken the governance of Dongting Lake as a main battlefield to tackle key problems, and effectively improve the construction of water ecological civilization in the Yangtze River Basin." Deng Lijia, director of the Hunan Provincial Department of Ecology and Environment, said that more than 96% of Hunan's areas belong to the Yangtze River Basin, and "Hunan, The four waters of Zi, Yuan and Li all flow into the Yangtze River through Dongting Lake, and the water ecology of Dongting Lake directly affects the Yangtze River Basin.

　　In the past six years, Hunan, with the determination of a strong man to break his wrist and extraordinary measures, has promoted the protection and restoration of the Yangtze River, the ten key areas and nine key areas of the Dongting Lake ecological environment, and the protection and governance of the Xiangjiang River. Sewage, chemical pollution, tailings pond pollution, etc. have been comprehensively tackled, and the stubborn pollution diseases have been eliminated one by one.

　　In Dongting Lake wetland, 386,400 mu of European and American black poplars were removed, and 444,200 mu of ruins, beaches and shorelines were restored and cleaned; 251 gravel piers were demolished and re-greened by Dongting Lake; in the Xiangjiang River Basin, Qingshuitang old industrial zone was closed and relocated. Crack the "chemical industry surrounding the river"... From the absence of Class III water in 2016, the water quality of Dongting Lake has stably reached Class III except for the total phosphorus index, and Dongting Lake is changing.

　　"The focus of the current wetland protection work has changed to continue to consolidate the results of remediation, strengthen protection and scientific restoration." Wu Jingjun, director of the Yuanjiang City Administration of the Dongting Lake Nature Reserve in Yiyang South, said that Dongting Lake wetlands focus on biodiversity protection, pay attention to The wetland ecosystem is stable and sustainable, and an all-round ecological security barrier is constructed.

　　From 0:00 on January 1, 2021, a "ten-year fishing ban" will be implemented in key waters of the Yangtze River Basin to reverse the trend of ecological environment deterioration.

In Hunan, a small fishing boat passing by the water or a person appearing by the water late at night can be identified and captured by the camera. The "smart fishery administration" monitors the situation in the prohibited waters in real time and better protects fishery resources.

　　Continue to carry out artificial breeding and release of fish, and implement a ten-year ban on fishing in the waters of the Hunan section of the Yangtze River, Dongting Lake and other waters; the implementation of the "Hunan Province Dongting Lake Protection Regulations" continues to promote ecological protection and restoration, and promote harmony between man and nature Symbiosis... In the chess game of protection and development of the Yangtze River Economic Belt, Hunan has gradually built an "ecological barrier".

　　"During the 14th Five-Year Plan period, we will continue to expand the governance of Dongting Lake to 'one lake and four waters', and finally achieve the goal of governance." Deng Lijia said that Hunan will continue to promote the construction of ecological civilization with "one river, one lake and four waters as the main battlefield" "Incorporated into the core content of economic and social development, as a key people's livelihood and practical affairs, it will make every effort to contribute to the development of the Yangtze River Economic Belt for a longer period of time.
