农业非点源污染研究进展和趋势

The Progress and Trends of Agricultural Non-point Source Pollution Research

根据国内外农业非点源污染研究现状,本文在探讨农业非点源污染内涵及其特征的基础上,简要总结了农业非点源污染负荷的估算模型,列举区域农业非点源污染风险评估的手段和方法,从不同角度归纳了农业非点源污染的控制技术,并提出了近期农业非点源污染急需研究的热点和趋势,以期为进一步的农业非点源污染管理和控制提供参考。

According to the current research on agricultural non-point source pollution at home and abroad, the connotation and feature of a-gricultural non-point source pollution were explored in this paper, and then the estimating model of pollution load was concluded briefly. Meanwhile, the paper also listed the means and methods of risk assessment of regional agricultural non-point source pollution and summed up the control technologies from different angles. Finally, the recent much-needed research hotspots and trends were put forward in order to provide reference for further management and control of agricultural non-point source pollution.
