摘　　要：中国已占水环境容量中,除了点源污染以外,非点源污染也占有相当比重,非点源污染负荷的定量化研究势在必行。国外对非点源污染的研究开始较早,成果也较成熟。从20世纪80年代以来,中国也逐渐认识到非点源污染的存在及其危害性,开始了非点源污染的控制研究。但是中国对非点源污染问题的研究现在尚处于初级阶段,多为借鉴国外模型。文章分析了国内外对非点源污染的研究方法和研究现状,介绍了适合中国国情的非点源污染负荷估算的方法,包括流域水文估算法、大尺度区域中非点源污染负荷估算的方法。Non - point pollution also accounts for quite proportion in addition to point pollution in our country＇s water environment capacity. Fix - quantity research of non - point source pollution has to be imperative under the situation. The research of non - point pollution in foreign countries is earlier and advanced than in China, The research was started 1980＇s in China, but it is in the preliminary state to study the problem of the non - point pollution in our country. Most methods have been employed from foreign countries. The research methods and the present situation in foreign countries and in China are analyzed. The non - point source pollution loading estimation methods which adapt to the situation of China is introduced.
