摘　　要：在分析了库区面源污染源构成的基础上,通过输出系数法进行了主要污染物的负荷估算,评估了库区农村面源污染对水库水质的影响。结果表明:库区面源污染主要为农业生产活动、禽畜养殖和农村生活,其中,农业生产活动的污染贡献率最大,所产生的TN、TP和COD污染占比分别达到83.45%、59.79%和90.38%。库区面源污染所排放的TN、TP和COD对水库污染物浓度的贡献率分别为31.91%、40.63%和19.08%。就污染负荷来看,TN和COD的污染负荷占比明显小于全国平均水平,TP污染负荷占比较为接近,大隆水库库区面源污染的控制优于全国平均水平。Based on the analysis of the composition of non-point source pollution sources in the reservoir area,the load of main pollutants was estimated by the output coefficient method,and the impact of rural non-point source pollution in the reservoir area on the reservoir water quality was evaluated.The results showed that the types of non-point source pollution in the reservoir area mainly included agricultural production activities,livestock breeding and rural life.Among them,agricultural production activities have the largest contribution rate of pollution,and the proportion of TN,TP and COD pollution generated were 83.45%,59.79%and 90.38%respectively.The contribution rates of TN,TP and COD discharged from non-point source pollution in the reservoir area to the concentration of pollutants in the reservoir were 31.91%,40.63%and 19.08%respectively.In terms of pollution load,the proportion of TN and COD pollution load was significantly lower than the national average level,and the proportion of TP pollution load was relatively close.The control of non-point source pollution in Dalong Reservoir was better than the national average level.
