| 摘 要： | 农业非点源污染正日益成为水体富营养化最主要的污染源,并已成为当前限制我国经济可持续发展的重要因素。笔者从农业非点源污染物迁移转化机制、非点源污染物的防控机制、非点源污染模型模拟、农业非点源污染研究中的尺度问题等方面对国内外研究进展进行了论述。提出我国非点源污染研究需在以下方面有所加强:(1)非点源污染物耦合作用下的运移;(2)转化机理及其界面行为过程机制研究;(3)不同空间尺度和格局农业非点源污染物的迁移转化规律;(4)适合我国不同区域特色的非点源污染机理模型研究。

| Abstract: | Agricultural non-point source pollution is becoming the most important source for water body eutrophication,and has become an important factor limiting sustainable development of China''s economy nowadays.In this paper,transfer and transformation mechanism,prevention and control means,model simulation and scale issues of agricultural non-point source pollution researches were summarized.In the end,several hot-spots that could be enforced in future were proposed as:(1)transfer and transformation mechanism of non-point source pollutants under combination;(2)behavior principle of non-point source pollutants between interfaces;(3)laws of movement and transformation of agricultural non-point source pollutants under different spatial scale and patterns;(4)non-point source pollution modeling suitable for different regional features. |
