鄱阳湖水利枢纽工程对长江干流下游补水影响分析

Study on Impacts of Poyang Lake Hydraulic Project Hydrating Effect of the Mid-lower Yangtze River

依据鄱阳湖控制站湖口水文站、长江中下游大通水文站、鄱阳湖星子水位站1956—2014年历年实测流量、水位资料,分析了天然状态下受长江上游控制性水利工程影响下鄱阳湖对长江下游的补水影响,并采用静库容模拟鄱阳湖水利枢纽实施后对长江干流下游的补水影响。通过天然状态和水利枢纽工程运行后补水影响分析比较,结果表明水利枢纽运行不仅有利于增加长江下游河道枯水期水资源量,维持下游河道的生态环境,而且在长江干流咸潮入侵、水污染事件等特殊情况下有应急补水的潜力。

The basis of hukou hydrological stations of poyang lake control station, the mid-lower Yangtze River chase hydrological station, poyang lake planetesimals gaging station from 1956 to 2014 calendar year measured data of flow, water level and analyses the natural condition under the influence of the upper Yangtze river controlling water conservancy projects was poyang lake to the Yangtze river downstream of the hydrating effect, and the capacity of the static simulation of poyang lake water conservancy hub after implementation of the Yangtze river downstream of the hydrating effect. Through natural state and after water conservancy hub project running hydrating effect analysis and comparison, the results show that water conservancy hub operation is not only beneficial to increase the downstream channel of the Yangtze river water quantity, water, maintain the ecological environment of downstream river channel, and the trunk of saline intrusion in the Yangtze river, the water pollution incidents have emergency repairs the potential and other special circumstances.
