摘要
2005年1月～12月,分别对抚仙湖主要的35条入湖河流进行了定点采样及化验分析,结果表明,入湖污染物TP:103.25 t/a,N-NH3:201.61 t/a,TN:862.67 t/a,SS:73 177.77 t/a;入湖河流水质综合评价为劣V类.从调查结果看,入湖河流是输送陆源污染物的主要通道,从源头控制污染物的流失及对河道进行综合治理是保护抚仙湖的关键.
Water samples taken from designed points in 35 branch-rivers were analyzed once a month in 2005.It showed that TP drained into FuxianLake was 103.25 ton per year;TN was 862.67 ton per year;N-NH3 was 201.61 ton per year;and SS was 73 177.77 ton per year.And water quality in tributaries of Fuxian Lake was judged as the worst.Because the river is the main channel to transport contamination from land,the key to protect Fuxian Lake is to bring the contamination of fountainhead into control and harness the waters in Branch-rivers.
