摘要
以南京外秦淮河为例,介绍河道淤积特征、水环境特征,针对河道存在的淤泥污染水质、影响行洪、威胁游船安全的问题以及其生态治理的必要性进行分析,提出河道生态治理工程方案。通过外秦淮河生态治理工程的实施,可有效减少内源污染,改善水环境,同时能拓浚河道断面,提高防洪排水能力。该工程可供类似河道生态治理参考。
Taking the Outer Qinhuai River in Nanjing as an example,the characteristics of siltation and water environment of the river are introduced,then the problems of silt pollution of water quality,affecting flood discharge,threatening the safety of cruise ships and the necessity of ecological management are analyzed.Finally,the ecological management project of this river is put forward.The results show that the endogenous pollution can be effectively reduced through the implementation of ecological treatment in the Outer Qinhuai River.And improve the water environment,expand the river section,and enhance the flood control and drainage capacity.The project can be used as a reference for similar river ecological management.
