农业面源污染防治研究现状与展望

农业面源污染是影响水环境质量的重要污染源,对水环境的污染贡献率逐年提高,逐渐成为制约农业可持续发展和实现农村现代化的环境瓶颈。文章在广泛调研国内外相关领域研究成果的基础上,综述了农业面源污染防治相关领域的研究进展,主要包括:农业面源污染物流失特性研究、土地利用方式影响研究、农业面源污染控制和治理技术研究、面源污染模型研究、现代电子信息技术的应用以及最佳管理措施(BMPs)的研究与实践等。最后,对农业面源污染控制领域未来重点研究方向进行了展望,并提出了相关建议。

Review on the Charictaristic and Control Measurements of Agricultural Non-Point Sourece Pollution

Agricultural non-point source pollution is an important source to water environment,and the contribute ratio to water pollution has increased annually,gradually become one of the environment bottlenecks which constraint the sustainable development of agriculture and rural modernization.Based on the extensive analysis of the relevent research results at home and abroard,have a review for the agricultural non-point source pollution prevention and control,including: the loss characteristics of agricultural non-point source pollution,the land usage,the technologie of agricultural nonpoint source pollution control and remediation,model research,the application of modern electronic information technology,the research and practice of BMPs(Best Management Practices),and so on.Finally,put forward the key research area and relevant proposals in the fields of agricultural nonpoint source pollution control in the future.
