| 摘 要： | 为了分析三峡水库的调洪运用对长江中下游干流水位的影响,采用成熟的预报模型对2010年7月中下旬长江上游地区发生的大洪水过程进行还原计算,分析了三峡水库的拦洪削峰作用.结果表明,洪水过程中,通过对三峡水库的合理调度,有效降低了长江中下游干流各站水位,其中宜昌-沙市河段水位降低约2.5 m,城陵矾-汉口河段水位降低约1.0 m,九江-大通河段水位降低0.3-0.5 m,沙市水位降到警戒水位以下,缓解了荆江河段和中下游干流的防洪压力,缩短了监利-汉口河段各站超警戒水位时间.

| Abstract: | By adopting the matured forecasting model,we conduct a returning calculation on the flood process in middle-late July in upper Yangtze River watershed,and analyze the effects of flood retention and peak reduction of Three Gorges Reservoir.The result shows that Three Gorges Reservoir operation reduced the water level of the main stream in every station on mid-lower reaches of Yangtze River effectively during the flood process.The water level dropped in Yichang-Shashi reach,Chenglingji-Hankou reach,Jiujiang-D... |
