摘　　要：根据对丽水市城区内河设立的10个控制断面的水质监测成果,利用标准指数法对现状水环境进行分析评价,并对主要污染因子进行排序。从内河水环境质量现状评价结果可以看出,丽水城区内河河网的水质很差,富营养化严重,除好溪堰河、明厦河、海潮河和丽阳坑上游个别断面水质稍好外,城区内河现状水质绝大部分为劣Ⅴ类水体,且属严重污染。从主要污染因子及污染源看,其主要污染因子是总氮和氨氮,主要污染源首先是城乡居民生活污染和畜禽粪便污染,其次为工业和农业面源污染。Based on water quality monitoring data from 10 control sections of inland rivers in Lishui urban area,Standard Index Method was used to analyze the current water environment and sort major pollution factors.Results suggest that the inland river network is poor in quality with serious eutrophication.Except the slightly better water quality in the Haoxiyan River,the Mingxia River,the Haichao River,and the upper reach of Liyangkeng,other inland rivers suffers from serious pollution with poor rating of GradeⅤ.In terms of major pollution factors and pollution source,total nitrogon and ammonia nitrogen being the largest pollution factors,residents＇ daily waste,livestock and poultry waste contribute most to river pollution,followed by industrial and agricultural area source pollution.
