摘　　要：阿什河流域农业非点源污染物等标污染负荷总量为5 572.96×106m3/a。不同污染源污染贡献比例:农田化肥占49.24%、畜禽养殖占35.10%、农村生活占14.69%、农作物秸秆仅占14.69%0.97%。污染物贡献量比例:TN占56.46%、TP占39.06%、COD仅占4.48%。对农业非点源污染的等标污染负荷量进行聚类分析,结果表明:阿什河流域按区域污染贡献大小可分为四类区域。Total quantity of equal standard pollution load of agricultural non-point source pollution is 5 572.96×106 m3/a in Ashi River basin.The ratios of pollution contribution for different pollution sources are shown as follows：chemical fertilizer is 49.24%,livestock and poultry is 35.10%,rural domestic wastewater is 14.69%,and crop straw is only 14.69%.The ratios of pollutants are shown as follows：TN is 56.46%,TP is 39.06%,COD is only 4.48%.This paper analyzes on equal standard pollution load of agricultural non-point source pollution with the method of cluster analysis.The results show that Ashi River basin can be divided into four regions according to pollution contribution.
