2020 the upper and middle reaches of the Yangtze River controlled reservoir group scheduling coverag baxia

In 2020, the upper reaches of Yangtze River Control of Reservoirs Dispatching coverage of 90%– environmental protection — people.com.cn original title: 2020, the upper reaches of Yangtze River Control of Reservoirs Dispatching coverage of 90% China news network October 9th news (reporter Zhang Yanling) in September, the Ministry of water resources released "Yangtze River Economic Zone Development plan", in the Yangtze River economic belt development the ecological environment of the Yangtze River, must be put in the first place, let the mother river of vitality. Recently, the Ministry of water resources, the relevant departments responsible person on how to implement the "Yangtze River Economic Zone Development Plan", grasping the Yangtze River protection to answer a reporter’s question. Q: as the upper reaches of the Yangtze River water resources group of heavenly stems and earthly branches are put into operation, how to strengthen the reservoir group scheduling, give play to the comprehensive utilization efficiency of water resources protection, flood control safety, ecological safety, water supply safety and navigation safety? The responsible person said, in order to strengthen the Yangtze River harnessing and development and protection, after years of efforts, the Yangtze River Basin has built a number of Three Gorges Reservoir as the core of the control of water conservancy and Hydropower Engineering, play a huge role in flood control, ecological protection, water supply, power generation, shipping etc.. Due to the operation of the reservoir group, the hydrological situation of the middle and lower reaches of the Yangtze River has changed a lot. The relationship between rivers and lakes presents a new situation, and the change of sediment erosion and deposition is more complex. To maximize the overall benefits of reservoir group since 2009, the Yangtze River Water Conservancy Commission carried out with Three Gorges Reservoir as the core of the research group of the Yangtze River comprehensive dispatching reservoir tributaries, formulated the "optimal scheduling scheme" of the reservoir upstream of the Yangtze River, the dry tributary of the Yangtze River 30 control reservoir joint dispatch, cumulative in the middle and lower reaches of water nearly 200 billion cubic meters, to ease the situation in the middle and lower reaches of the dry season, improve the water environment, the effective protection of aquatic resources and population. Since this year, the Yangtze River Basin flood occurred in 1998, June 30th to July 24th, the upper reaches of the Yangtze River in Chenglingji above the main reservoir impoundment volume of 22 billion 700 million cubic meters, the Three Gorges Reservoir 7 billion 500 million cubic meters, effectively reduce the downstream water level, reduce the loss of flood disaster. The next step is to continue in accordance with the "Hennessy to flood control, water diversion and power transfer to professional subject to the comprehensive, the part to the whole" principle, through the improvement of laws and regulations, improve the management system, establish a compensation mechanism to strengthen technical support, strengthen supervision and management measures, and gradually establish a stakeholder with wide participation in irrigation scheduling control hydropower engineering consultation mechanism and management system, and strive to 2020, the upper and middle reaches of the control of joint operation of reservoirs to achieve 90% coverage, better play the Yangtze River water reservoirs in the heavenly stems and Earthly Branches of flood control, water supply, environmental protection and other comprehensive benefits. At the same time, improve the emergency dispatch plan, make special dry season, water pollution, water safety accidents, accidents and other emergency response project.
