【摘要】 介绍HSPF模型的主要结构和功能,通过对该模型参数的灵敏度分析和参数调整,利用滇池流域各入湖河流1988,1989年的水质监测数据及相关统计资料,分别对该流域的水文、水质过程进行了模拟.结果表明,SS是滇池流域非点源污染的首要污染物,大约80%的入湖SS来自非点源.在枯水年(1988年),非点源贡献了约1/3的TN、TP入湖负荷量.而BOD的主要贡献者则是点源污染.更多还原

【Abstract】 This main structure and function of HSPF was introduced. According to sensitivity analysis and adjustment of model parameters, the hydrological and water quality process of the Lake Dianchi basin were simulated using observed and statistical data in 1988 and 1989 for each river. SS was the primary pollutant of non-point source pollution in the basin, about 80% of SS coming from non-point source pollution. About 1/3 total nitrogen and phosphorus were contributed by non-point sources pollution in low flow year (1988). But the main contributor of BOD was point source pollution.更多还原
