【摘要】：三峡工程是我国有史以来建设的最大型的工程项目,具有防洪、发电、航运等方面巨大的经济和社会效益。然而,三峡工程的运用不可避免地会对原有江河湖泊水文情势产生一定影响。通过建立长江中下游(宜昌~大通)水沙模拟模型,定量分析了三峡工程运用对鄱阳湖水位的影响。三峡水库蓄水期(9月中下旬~11月),三峡水库下泄流量比水库运用前减少3 000~6 000m3/s,湖区各站水位最大降幅为0.7~1.9m,平均降幅0.4~0.9m。以此为基础,通过典型调查分析了三峡水库蓄水对鄱阳湖区农田灌溉用水和城镇供水的影响,提出了消除或降低影响的对策措施。研究结果可为鄱阳湖及长江中下游地区经济社会可持续发展和鄱阳湖综合治理提供科学依据和技术支撑。
[Abstract]:The Three Gorges project is the largest project in the history of China's history, which has great economic and social benefits in the fields of flood control, power generation, shipping and so on. However, the application of the Three Gorges Project will inevitably have a certain impact on the hydrological situation of the existing rivers and lakes. The water and sediment simulation model of the middle and lower reaches of the Yangtze River (Yichang ~ Datong) is established, and the influence of the Three Gorges Project on the water level of Poyang Lake is quantitatively analyzed. During the period of Three Gorges reservoir (9 months ~11 months), Three Gorges reservoir discharge reduced by 3 000~6 000m3/s than the reservoir before use, the biggest drop of water level of Lake 0.7~1.9m, by an average of 0.4~0.9m. Based on this, the influence of Three Gorges reservoir impoundment on farmland irrigation water and urban water supply in Poyang Lake area is analyzed based on typical investigation, and Countermeasures for eliminating or reducing the impact are put forward. The research results can provide scientific basis and technical support for the sustainable economic and social development of Poyang Lake and the middle and lower reaches of the Yangtze River and the comprehensive control of Poyang Lake.

【正文快照】： 鄱阳湖位于长江中、下游交接处的南侧、江西省北部,是我国第一大淡水湖。鄱阳湖上承赣、抚、信、饶、修五大河(简称“五河”),下接浩浩长江,是长江中下游仅存的两个通江大湖之一。鄱阳湖湖水呈季节性涨落,洪水位变幅大,每年4月起,鄱阳湖水位抬升,大小湖汊和大湖融为一体;10月
