摘　　要：长江三角洲(以下简称“长三角”)是我国重要商品粮基地,但近年来农业面源污染问题日益突出。文章结合实地调查、政策解析、工程设计、效益评估等方式,提出了关于推进我国长三角地区稻田退水零直排工程建设的建议,明确了稻田退水零直排工程建设的政策适应性,以及长三角地区实施稻田退水零直排的重要性,对稻田退水零直排工程建设的基本原则、设计要求、模式选择与投资成本、可预期的生态经济效益进行了全面分析,以期为我国面源污染防治与农业绿色优质发展提供决策支持。The Yangtze River Delta region is an important commodity grain production area in China,but has been suffering from agricultural non-point source pollution issues in recent years.This study puts forward a suggestion on promoting the construction of zero-direct discharge(ZDD)engineering for agricultural wastewater from paddy fields in the region.This suggestion is based on the field investigation,policy analysis,engineering design,and economical evaluation,which clarifies the policy adaptability and the construction importance of the ZDD engineering.At the same time,this suggestion shows the basic principles,design requirements,mode selections,investment cost,and expected ecological economic benefits of the ZDD engineering.It is expected to provide decision support for China to mitigate the non-point source pollution and enhance agricultural green development.
