摘　　要：为研究城市浅水湖泊水生态环境状况,以邯郸市南湖为例,采用单因子评价法、综合污染指数法和综合营养状态指数法,按照《地表水环境质量标准》(GB3838-2002)Ⅲ类水体水质标准对水环境质量进行评价和分析。结果表明,氮、磷是南湖水体的污染控制因子,各采样点的TN、TP均不能满足Ⅴ类水体的水质要求;生活污水、工业废水和岸边垃圾堆放是南湖的主要污染源,相应采样点的污染指数分别达到了3.0和2.2;南湖水质整体处于轻度富营养水平,距污染源较近区域已处于中度富营养水平。South Lake in Handan City, typical of shallow urban lake with only 1.3m water depth on the average, was studied in this paper for evaluating the status of water quality by methods of single-factor appraisal, comprehensive pollution index and nutrient index. With the water quality monitoring involving 11 sampling sites all over the Lake which began from April to October 2013, and the analytic data of water quality, the evaluation was carried out in accordance with the related national standard Environmental Quality Standard for Surface Water （GB3838-2002）. Results showed that nitrogen and phosphorus were the main pollution factors to be controlled in South Lake as all the data from the monitoring sites indicated concentrations of both TN and TP exceeded the limits of Class V in GB3838-2002. According to the field survey, emissions of domestic sewage and industrial wastewater and the dumping of garbage on the lake-shore were the main sources causing water pollution, with the pollution indexes being 3.0 and 2.2 respectively. The appraisal based on comprehensive nutrient indexes showed that the Lake, as a whole, still remained at the slight eutrophication level, while in the places close to pollution sources the situation was aggravated to median level.
