摘要
对抚仙湖16条主要入湖河流中CODcr在枯、丰、平水期的变化情况进行监测和分析,结果表明:抚仙湖的入湖河流CODcr污染严重,暴雨期CODcr浓度高于非暴雨期,特别是暴雨初期.分析统计结果还表明,面源污染是抚仙湖水质污染的主要来源,因此从源头上控制面源的产生,减少地表径流入湖污染物负荷量是保护抚仙湖优良水体的关键.
The 16 major inflow rivers of the Fuxian Lake were monitored for the concentration of CODcr in dry seasons,low water,and high water seasons.The result shows that the inflow rivers are heavily polluted by CODcr,which has a higher concentration in rainstorm season than other times,especially during the early period.After statistical analysis,it is found that non-point pollution is the major source of water pollution of the Fuxian Lake.Therefore,the key for the Fuxian Lake to keep clean water body is to reduce runoff pollutant into the lake by controlling the generation of non-point pollution sources from headstream.
