摘　　要：通过对辽宁省清原县大苏河乡2002—2007五年间农业非点源污染基础资料的调查,对大苏河乡农业非点源污染负荷以及现状进行评价。首先利用输出系数法得出构成大苏河地区农业非点源污染负荷的各个村落的贡献大小,运用SPSS软件的聚类分析可知,根据污染负荷的程度不同,大苏河乡的10个自然村共分为三类,其中以大苏河村和南天门村农业非点源污染负荷最为严重;又根据等标污负荷法,得出浑河水系的大苏河段农业非点源污染负荷各污染源的贡献率,且从大到小依次是:畜禽养殖、农田化肥、人类生活。从而为大苏河地区制定控制农业非点源污染发生的措施方面提供了科学依据。According to the investigating of five years＇ agricultural non - point source pollution in Dasu River, Qingyuan County, Liaoning Province, and this paper evaluate the actuality and loadings of agricultural non - point source pollution. First the contribution of every country was got by the export coefficient modeling approach. They were divided into three parts by the cluster analysis in SPSS software, and the main pollution loading countries were Dasuhe county and Nantianmen county. Also in accordance with the method of equivalent pollution loading, the contributions of pollution sources which are livestock farm, fertilizer farm, and people living were known. In addition, non - point pollution has showed its specific characteristics in Dasu River of Hun River, which provided scientific basis for controlling agricultural non -point source pollution.
