摘要
松华坝水库是云南省昆明市的主要饮用水源,饮用水源的水质变化直接关系到昆明市市民的身体健康。1996-2005年来,松华坝水库的水质由“九五”期间的Ⅲ类,在“十五”后期变为令人担忧的Ⅳ类,主要污染物为总氮、总磷。为有效防治松华坝水库水质污染,针对主要污染源,采取措施开展有效防治,从水质一水文相关分析和保护区产业发展的角度,对松华坝水库以及入库主要河流的主要污染物总氮、总磷变化做了分析,间接证明了松华坝水库的氮、磷主要来源于面源(非点源)。
Songhuaba reservoir is an important water source of Kunming,Yunnan province. The water quality of Songhuaba reservoir has a very direct relationship with the population's health lived in Kunming city. Between 1996 and 2005, the water quality had degraded from Ⅲ to Ⅳ. The main contaminant index is TN and TP. This paper had a correlation analysis between the rainfall and water quality,and also had an analysis on the water quality change of the inflow river and the reservoir. After that the business development status is also analyzed. From these analysis,this paper had proved that the main source of nitrate and phosphate pollutant in Songhuaba reservoir is nonpoint source.
