摘　　要：三峡等长江上游水库建成运用后,将影响中下游沿江地区水资源配置格局,在调查分析长江中下游沿江地区灌溉、供水取用水现状的基础上,分析了长江干流,特别是枯水期的取水需求。为保障中下游沿江地区供水安全,对上游水库调度提出了建议,包括每年枯水期、特别是遇特枯年份,三峡等水库应为长江中下游适当补水;每年灌溉期间,要求蓄水过程不能太短,且保持一定水平下泄流量,在用水紧张期时加大下泄流量。Water resources allocation pattern will be changed in the areas along mid-lower Yangtze River after completion and operation of reservoirs such as the TGP in its upper reaches.Based on survey of the status of water use and supply in cities and irrigation areas,we analyze the water demand for the river mainstream especially in dry season.Suggestions for reservoir operation of upper Yangtze River are proposed to guarantee the water supply safety in the areas along mid-lower Yangtze River,including appropriate water supplement from TGP to mid-lower of Yangtze River in dry season,especially in an extremely dry year,relatively long period of impoundment and a certain discharge volume during irrigation.And in the period of water shortage,the discharge volume should be increased.
