摘　　要：非点源污染是目前影响水环境质量的主要污染源之一,本文对国内外水环境非点源污染负荷的估算方法进行了总结和分析,介绍了污染分割法、输出系数法、平均浓度法等经验统计方法和ANSWERS、BASINS、SWAT等分布式模型估算方法的特点。在此基础上,提出了如何选用合适的非点源污染负荷估算方法。Non-point source pollution was a major source that influenced water quality.Based on the comprehensive literature review at home and abroad,a review of recent research advancement in non-point source pollution loads estimation methods was presented.The estimation methods could group into two types of experiential statistical method and model estimation method.The principles and applications of experiential statistical methods,such as Pollution Division,export coefficient model,mean concentration method,were introduced,and the characteristics and applications of major estimation models,such as Areal Non-point Source Watershed Environment Response Simulation（ANSWERS）,Better Assessment Science Integrating Point and Non-point Sources（BASINS） and Soil and Water Assessment Tools（SWAT） were summarized and analyzed.Finally,the method of estimating the load of non-point source pollution was put forward.
