摘　　要：白甫河作为贵州省毕节市的母亲河,受城市发展及人口扩张影响,城区河段水环境现状日益严峻。为了解白甫河水环境现状,科学制定生态修复与保护方案,本文应用DHI(丹麦水利研究所)MIKE11软件构建白甫河毕节城区段一维水动力-水质耦合模型,从水动力和水质角度分析评价河段水环境现状。结果表明:采用MIKE11能直观反映研究区沿程的水位、流量、水质变化情况;可通过分析水位、流量、水质沿程变化图确定河道生态修复及水质治理的关键控制段,选定更适宜的河流生态修复技术,为城区河段制定水环境保护措施提供参考依据。Baifu River is the mother river of Bijie City,Guizhou Province.Affected by the urban development and population expansion,the water environment in the urban reaches of Baifu River is becoming worse.In order to understand the water environment status of Baifu River and scientifically formulate ecological restoration and protection plans,this paper applied DHI MIKE11 software to build a one-dimensional hydrodynamic and water quality coupling model of Baifu River Bijie Section,and analyzed and evaluated the water environment status of the river section from the perspective of hydrodynamic and water quality.Results showed that,MIKE11 can directly reflect the changes of water level,flow and water quality along the study area;through the map of changes of water level,flow and water quality along the study area,the key control sections of river for ecological restoration and water quality control can be determined,and more suitable river ecological restoration technology can be selected.
