中文摘要：

水环境非点源污染已引起严重的生态环境问题,非点源污染的量化是当今国际研究热点,数学模拟是研究非点源污染最直接有效的途径之一,建立以实用性为目标的非点源污染机理模型已成为管理和控制非点源污染的有效手段。本文阐述了国内外非点源污染模型的发展、功能、存在的问题,及构建非点源污染机理模型的思路,最后展望了非点源污染模型研究的发展趋势。

英文摘要：

Water environmental nonpoint source pollution has caused serious eco-environment problems, and the quantitative identification of nonpoint source pollution is an international research focus, of which the most direct and effective means is mathematical simulation, and the establishment of a practically-aimed non-point source pollution mechanism model has become an effective means for nonpoint source pollution management and control. The development, functions and current problems of domestic and international nonpoint source pol-lution models, along with the construction approaches of nonpoint source pollution mechanism model, are brief-ly described, and the future studies are prospected in this paper.
