摘要
于2005年全年和2009年6～7月,分别对抚仙湖北岸的水质及主要入湖河流中的TN、TP和COD污染因子进行了监测与分析.监测结果表明,抚仙湖中TN和TP浓度随着岸距的减小而增大,说明抚仙湖北岸的水质与入湖河流的污染程度有着直接的关系,而在诸多入湖河流中,梁王河、东大河、代村河对抚仙湖北岸的污染较为严重.监测结果还表明,与2005年同期相比,2009年的抚仙湖北岸的水质有了明显好转,但仍未达到I类水质标准,因此,继续加强北岸入湖河流的治理显得非常关键.
The analysis of water quality of Lake Fuxian and the detection of TN,TP and COD pollution factors in inflow rivers on north bank of the lake made in 2005 and the period from June to July of 2009 show that the concentration of TN and TP increases with reducing distance from lakeside,indicating a clsoe relationship between the water quality of Lake Fuxian and the pollution of its inflow rivers.Of its inflow rivers,Liangwanghe river,Dongdahe river and Daicunhe river are heavily polluted.The results also show that compared with 2005,although remarkable improvement was made in 2009,the water quality of Lake Fuxian is still below the standard of Grade I.Therefore,it is critical to reinforce the management of inflow rivers on north bank.
