摘要
最佳管理措施(BMPs)对控制农业面源污染具有重要意义。本文从两方面归纳中国BMPs的研究现状:基于污染物关键源区的位置,分为不同类型的BMPs(源头控制、迁移途径阻截、末端治理);根据措施实施的环境背景,分为不同空间单元(流域、行政区域)上的BMPs组合。对现有的措施分析其控污机理和净化效果,指出当前研究存在着理论研究薄弱、缺乏成本-效益分析、措施优化组合不够、环境效果评价不足等问题。着重指出今后应从以下5个方面加强研究:BMPs管理体系建设,措施研发与技术集成,模型模拟研究,尺度转换模式,BMPs效益评价。本文旨在为提高中国BMPs构建与研究水平,同时为中国农业面源污染防控和水环境改善提供理论借鉴和科学依据。
Best management practices （BMPs） are of significance in controlling agricultural non- point source pollution. This paper reviewed the research progress of BMPs in China from the aspects of 1 ） the classification of BMPs types （ source control, migration pathways interception, and terminal treatment） based on the position of key pollutants source, and 2） the assemblage of BMPs at spatial unit scales （watershed and administrative area） based on the environmental background of implementing BMPs. It was pointed out that the existing BMPs researches were mainly insufficient in theory, cost-benefit analysis, measurements optimal assemblage, and envi- ronmental effect evaluation. Accordingly, the issues that should be put into priority in the future would be the theory system construction, model simulation, measures research and development and technologies integration, spatial-scale transformation, and benefit evaluation. This paper could benefit the improvement of BMPs construction level and research quality in China, and also, provide theoretical reference and scientific evidence for the prevention and control of agri- cultural non-point source pollution and the improvement of water quality in China.
