Abstract:: The agricultural non-point source pollution load, source apportionment and pollution sensitivity were deeply analyzed and the pollution control priority area was identified by the inventory analysis method and equivalent standard pollution method with the help of GIS in Ash River Basin. The results showed that the order of the contribution of each pollution source was fertilizer > livestock > living > soil erosion > straw, and the equivalent standard pollution load ratio was in the order of 67.46% > 16.24% > 12.21% > 2.69% > 1.40%. The fertilizer pollution contribution was the highest in the study area except Xing-Fu town with highest living pollution. The Xiangyang, Liaodian, Sheli, Yangshu and Shuangfeng towns, which were located in the middle reaches of the Ash River Plain, were indentified the prior regions for agricultural and rural pollution control area because the TN and TP concentrations were excessively high due to using a large number of chemical fertilizers.
