摘 要：
在阐述稻田退水氮磷面源污染严重性及沟渠结构与功能的基础上,分析了沟渠底泥吸附、植物吸收、微生物分解和协同作用等主要净化机理,探讨了沟渠植物种类选取、沟渠基质类型筛选、沟渠结构的合理设计以及充分利用毗邻生态单元构建生态处理系统4种沟渠改造措施,指出在沟渠工程化建设的同时宜采用人工强化技术,可有效增强沟渠生态与服务功能;从生态学及景观生态学角度,提出生态拦截型沟渠、溪流式接触氧化沟渠、多级消减沟渠等3种新型生态型沟渠的应用。建议在沟渠的改造、利用、管理上要实施合理的监管制度,对新型沟渠的建设相关部门要出台相关法律法规及设计规范;同时,在理论研究的基础上进行实验室模拟分析,为实践工程提供数据支撑及科学指导。

摘 要：
To improve the removal rate of pollutant and enhance the ecological function effectively, four strengthening measures were discussed, including species selection of ditch plant, filter type of ditch matrix, reasonable design of ditch structure and constructing ecological treatment system with adjacent wetlands or ponds unit. Furthermore, from the perspective of ecology and landscape ecology, the ecological ditch system with interception function, stream type contact oxidation ditch and multistage reduction ecological ditch were introduced. Finally, it was advised that reasonable regulatory systems on the transformation, utilization and management of the ditch should be carried out, and relevant laws and regulations and design specifications on the construction of new ditches should be established; Meanwhile, theoretical research works should be carried out to conduct laboratory simulation and provide data support and scientific guidance for practical engineering.
