浙东河网水质改善措施研究——以上虞、余姚、慈溪河网为例

浙东地区位于长江三角洲经济区的杭州湾南岸，而且其中的萧绍宁平原河网水质普遍较差。浙东引水工程是解决萧绍宁平原及舟山市水资源短缺问题的系统水利工程，曹娥江至慈溪引水工程是浙东引水专项工程，该工程不仅可向上虞、余姚、慈溪提供优质的曹娥江径流，还可明显改善引水工程沿程河网的水环境。在建立河网水质数学模型的基础上，以改善该区河网水质为目的，根据环境远期目标，推荐最佳方案。

Research on improvement measures of water quality in estern Zhejiang——Taking Shangyu City,Yuyao City and Cixi City river networks as example

Eastern Zhejiang Province is a part of the Yangtzer River Delta economic region.The water quality of river network is bad commonly in Xiaoshaoning Plain.Water diversion project to eastern Zhejiang Province is a systematic hydraulic engineering resolving the problem about shortage of water resources in Xiaoshaoning Plain and Zhoushan City,in which water diversion from Cao'e River to Cixi City is a special project.Not only the project could provide excellent Cao'e River runoff for Shangyu City,Yuyao City and Cixi City,but also could improve the water environment of the river network along water-diversion project.Water-quality modeling of river network is constructed in this paper aiming to improve the water quality of river network in this region.According to the environmental goal,it recommends the best scheme.
