摘　　要：洞庭湖四口河系地区洪涝灾害频繁,防洪压力大,同时随着四口分流量逐年减小和季节性断流,加之水环境污染,四口河系地区季节性、水质性缺水问题严重。水利部公益性行业科研专项经费项目"洞庭湖四口河系防洪、水资源和水环境研究"由湖南水利厅牵头完成,取得了丰富的研究成果。通过项目研究,构建了洞庭湖四口河系水沙数值模型、区间洪水模型、水环境分析模型,分析了三峡工程不同运行方式下四口河系河道演变以及水资源和洪水的演变;在模型研究的基础上,结合水质监测资料、卫星遥感影像等,综合分析了三峡工程运用对四口河系地区防洪、水资源、水环境等方面的影响;在综合防洪、水资源和水环境分析结果的基础上,构建了洞庭湖四口河系地区综合调控体系。The flood is a serious problem in the region of Dongting Lake along Yangtze River.At the same time,the water resources shortage and the water environment are becoming worse and worse because the discharge from Yangtze River into the Dongting Lake is becoming smaller and smaller.The aim of this work is to solve these problems.This paper built a water-sediment model,a hydrological model and a water environment model,and analyzed the change of flood,water resources and water environment after the completion of the Three Gorges project in the region of Dongting Lake along Yangtze River.As well,this paper presented an integrated regulation and control system for flood control,water supply and water environment protection.
