太湖流域农田灌排系统生态化改造技术及相关标准

Ecological transformation technology and related standards of farmland irrigation and drainage system in Taihu Lake Basin

农田面源污染已成为中国农业绿色发展以及水环境质量改善的主要限制因子,如何保障国家粮食安全的同时有效减少农田面源污染是“十四五”的关注重点。本研究结合中国高标准农田建设的最新需求,指出了农田灌排系统生态化改造是高标准农田建设与面源污染防控的有机结合点,重点阐述了农田灌排系统生态化改造的建设目标、基本原则、适用技术和相关标准,并提出了当前农田灌排系统生态化改造的主要研究方向,以期为太湖流域生态农田建设提供相关参考,促进农业面源污染防控与高标准农田的融合,助推中国耕地数量、质量、生态“三位一体”保护。

Farmland non-point source pollution in China has become the main limiting factor for the green development of agriculture and the improvement of water environment quality.How to ensure national food security and effectively reduce farmland non-point source pollution is the focus of the 14th five-year plan.Based on the latest requirements of high-standard farmland construction in China,this paper pointed out that the ecological transformation of farmland irrigation and drainage system was the organic combination of high standard farmland construction and non-point source pollution prevention and control.Construction objectives,basic principles,applicable technologies and relevant standards of farmland irrigation and drainage system ecological transformation were discussed emphatically,and the main research direction in the future was put forward.It is expected to provide relevant reference for the construction of ecological farmland in Taihu Lake Basin,promote the integration of agricultural non-point source pollution prevention and control and high-standard farmland,and boost the trinity protection of quantity,quality and ecology of arable land in China.
