Huang Lanxiang, a member of the National Committee of the Chinese People's Political Consultative Conference, a member of the Standing Committee of the Hunan Provincial Party Committee, and Minister of the United Front Work Department of the Provincial Party Committee, who once served in Yueyang, Hunan, has always paid attention to the comprehensive management of the "Kidney of the Yangtze River" Dongting Lake's water environment and the construction of ecological balance.
During the National Two Sessions this year, Huang Lanxiang called for the inclusion of major projects identified in the "Dongting Lake Comprehensive Treatment Plan for the Water Environment" into the relevant special plans of the country's 14th Five-Year Plan.
Dongting Lake is the second largest freshwater lake in China and the most important storage lake and wetland in the middle reaches of the Yangtze River. It plays a huge role in purifying the environment, regulating water levels, and maintaining ecological balance.
However, the ecology and environment of Dongting Lake have been severely damaged in the past under the extensive development mode.
In 2018, 7 departments including the National Development and Reform Commission of China and the Ministry of Water Resources issued the "Dongting Lake Water Environment Comprehensive Management Plan", which requires the protection of the water quality of Dongting Lake, continuous improvement of the ecological environment of the Dongting Lake basin, and no major development, strengthening the protection and restoration of the water ecology , To realize the harmonious symbiosis between man and nature.
Strive to achieve the goal of building a beautiful Dongting Lake by 2035.
Withdrawal or relocation of 8,827 large-scale breeding farms, clean up 228,800 mu of poplar trees, dismantle illegal short fences, and severely stop the excessive mining and sand dug on Dongting Lake... Now, through the "scraping bone healing" type of heavy blow After the renovation, the blue waves and rippling waves reappeared in the Dongting of Eight Baili, and the scene of the huge sand dredging boat roaring over the lake and going all night is hard to see.
In recent years, Huang Lanxiang has led a research team to Yueyang to investigate the ecological management of Dongting Lake and understand the construction of the Dongting Lake ecological economic zone.
In an interview with reporters, she said that after nearly 6 years of rectification, Hunan has fundamentally reversed the trend of deterioration of the ecological environment of Dongting Lake.
In 2020, the average concentration of total phosphorus in Dongting Lake will drop by 9.1%, which is about 47% lower than in 2015.
"Hunan continues to improve the ecological environment of the wetland in Dongting Lake, and the beautiful scenes of egrets flying and finless porpoise prancing again. Elk populations and wintering migratory birds are also slowly increasing." Speaking of Dongting Mother Lake, Huang Lanxiang will calmly slow down. Speed, showing nostalgia for that piece of lake water.
"However, the current task of comprehensive treatment of Dongting Lake's water environment is still under great pressure, and the overall water quality is still Grade IV. Phosphorus control and phosphorus reduction is still a tough battle; the conversion of new and old kinetic energy is not smooth, and the economic transformation and upgrading needs of Dongting Lake are urgent." Huang Lanxiang suggested that the policy resources of various ministries and commissions should be integrated, and key support should be given to the Dongting Lake area in key river basin management, wetland ecological restoration, and green development.
Dongting Lake swallows the Yangtze River and accepts the four waters of Hunan, Capital, Yuan, and Li. With its huge flood capacity, it has turned floods into danger for countless times in history, and ensured that the vast areas of the middle and lower reaches of the Yangtze River were turned from danger to safety.
However, the accumulation of sediment and changes in the relationship between rivers and lakes have caused the "kidney of the Yangtze River" Dongting Lake to suffer from "kidney stones". Many connected rivers have been obstructed, and the capacity of water storage and water passing has also been weakened.
Implementing large-scale dredging and supporting construction engineering measures to fundamentally restore the "kidney function" of Dongting Lake, and improving the water environment of Dongting Lake is urgently needed.
An important water transportation channel connecting Hunan and Hubei provinces, Jianghan Plain and Dongting Lake Plain is being planned.
It is one of the “four vertical and four horizontal” backbone high-level water transportation channels in the national comprehensive three-dimensional transportation network. The construction content includes river dredging projects, backbone river-lake connection projects in the shoal, etc., which is to adjust the relationship between the Yangtze River and Dongting Lake and restore the ecological environment of the Yangtze River. Key project.
"At present, Hunan aquatic germplasm resources demonstration, site planning, land pre-examination, geological disasters and mining, and wetland park impacts have been completed. Environmental impact assessment, flood assessment, and soil and water conservation have been commissioned." Huang Lanxiang said that it is recommended to increase coordination. Leading from the national level, the advancement of the project has entered a substantive stage.
