摘　　要：研究优化了农业面源污染发生潜力评价(APPI)的指标体系,增加了COD产生指数并对人畜负荷指数的相关参数进行调整,并用改进后指数系统结合自然间断点分级法对常州市6个行政区的非城镇用地区域进行了农业面源污染发生潜力评价及优先控制区识别。This study improved the evaluation of agricultural non-point source pollution potential(APPI) system.The chemical oxygen demand production index was increased and the relevant parameters of the human and animal load index were adjusted.The improved APPI system combined with the natural breakpoint method was used to evaluate the potential of agricultural non-point source pollution and identify the priority control areas in Changzhou City without urban areas.

关 键 词：农业面源污染 发生潜力评价 APPI模型 优先控制区
