摘　　要：随着经济发展和城市化进程的加快,城市河流污染越来越严重,并逐渐成为入湖污染物的最主要来源。新运粮河作为流经昆明市区的典型城市河流,同时也是滇池北岸污染最严重的河流,是滇池草海的主要污染来源。文章结合2010年昆明市完成的新运粮河截污工程,针新运粮河城市入湖河流不同段落、不同层次以及其周边环境特点,充分利用河流的有效空间,开展了系列河流沿程生态修复减污技术的构建和工程示范。通过系列的原位生态修复技术、旁路生态修复技术和河口湿地生态修复技术与工程,使污染河水通过河流沿程减污,减少入湖污染的量,最终实现了新运粮河入湖河口水质接近地表水Ⅴ类的目标。Increased economic growth and urbanization process is leading to growing pressure on urban river, which has already been a main pollutant source in lakes. As a typical urban river that flows through the Kunming City, Xinyunliang River is the most severely polluted river in north area of Dianchi Lake and it becomes a main pollutant source for Caohai area of Dianchi Lake. In this paper, a series of demonstration projects on ecological remediation along the river route were presented.Based on Kunming sewage interception project in 2010, these projects were conducted in terms of different reach of Xinyunliang River and their surrounding environment. After implementing of in situ, bypass and estuarine wetland ecological remediation technologies, the pollutant in Xinyunliang river was gradually eliminated along the route until the estuarine water reached a Ⅴ class of the surface water before it flows into Dianchi Lake.
