我国生态沟渠控制农业面源污染研究进展
Research Progress of Ecological Ditches to Control Agricultural Non-Point Source Pollution in China

随着经济的发展，点源污染逐渐被重视和得到治理，使得面源污染在环境污染中所占的比例越来越大，我国农业面源污染已成为当前环境污染的重要影响因素，制约农业可持续发展和危害农村生态环境。本文通过对国内外关于典型农业面源污染控制技术——生态沟渠进行系统梳理，并重点阐述了生态沟渠控制对农业面源污染的影响机制和控制效果评估的发展方向，以期为生态文明建设和农业面源污染防控提供借鉴。明确生态沟渠控制农业面源污染的影响机制，建立多尺度下生态沟渠对农业面源污染的控制效果评估，是全面落实流域生态保护和高质量发展重要讲话重要指示精神、全面打好污染防治攻坚战的具体体现。
With the development of economy, point source pollution has been gradually paid attention to and controlled, which makes the proportion of non-point source pollution in environmental pollution more and more large. China’s agricultural non-point source pollution has become an important factor affecting the current environmental pollution, restricting the sustainable development of agriculture and endangering the rural ecological environment. This paper systematically combs the typical agricultural non-point source pollution control technology at home and abroad—ecological ditch, and focuses on the development direction of the impact mechanism of ecological ditch control on agricultural non-point source pollution and the control effect assessment, so as to provide references for the construction of ecological civilization and the prevention and control of agricultural non-point source pollution. Clarifying the mechanism of ecological ditches to control the impact of agricultural non-point source pollution and establishing the evaluation of the control effect of ecological ditches on agricultural non-point source pollution at a multi-scale is the concrete embodiment of fully implementing the spirit of the important speech and the important directive on the ecological protection and high-quality development of the river basin, and comprehensively fighting the battle of pollution prevention and control.
