用经验系数法和等标污染负荷法，借助GIS技术对阿什河流域农业非点源污染负荷、来源解析及其对境内水质造成影响进行深入分析。结果表明，在总量上各污染源对阿什河水质污染影响程度是：化肥施用>畜禽养殖>农村生活污染>土壤侵蚀>秸秆污染，其等标污染负荷比分别为67.46%>16.24%>12.21%>2.69%>1.40%；阿什河干流自上游到下游水质不断恶化，其中TN、TP浓度在中下游地区的丰枯水期均达到劣V类水平；高化肥施用量是研究区水质恶化的主要原因。

In this paper, the empirical coefficient method and equivalent standard method were conducted to analyze the agricultural non-point source pol ution load, source apportionment and its effect on the water quality with the help of GIS in Ash River Basin. The results showed that the contribution of different agricultural non-point sources was chemical fertilizer>Livestock>living>soil erosion>straw and the equivalent standard pol ution load proportion was 67.46%>16.24%>12.21%>2.69%>1.40%. Water quality condition from the upstream to the downstream was worsening and the TN and TP concentration actual y came to bad V class. The high TN and TP concentration caused by excessive chemical fertilizer became the main reason for the deterioration of water quality.
