摘　　要：介绍了将农田中坑塘湿地改建用于储存降雨径流和农田灌溉排水进行回用的水循环系统构建方法,在提出水循环调蓄湿地体积估算方法的基础上,构建了调蓄湿地水循环利用系统,分析了高效净污载体、微生物筛选与附着、水生植物群落配置和水动力微循环交换系统等水质净化技术,指出区域降水量和降雨历时是影响水循环调蓄湿地体积和循环水利用量的重要因素。对上海崇明水稻田循环调蓄湿地系统进行了设计与构建,循环调蓄湿地运行后共节约灌溉水量6239.9~9359.9 m^(3)。In this paper,the construction methods of water recycling system by the reconstruction of pond or wetland for storing rainfall runoff and reusing of irrigation drainage were introduced.The calculation method and design basis for the volume of water recycling reservoir were given.Based on the calculation method,the water recycling system of regulation and storage wetland was constructed.The water quality control techniques in the water recycling wetlands were also introduced,including the efficient purification carrier,screening and attachment of microorganisms,aquatic plant community arrangement,and hydrodynamic microcirculation exchange system.It was found that regional rainfall and rainfall duration are the important factors affecting reservoir volume and water recycling capacity.The design and construction of the cyclic regulation and storage wetland system in Shanghai Chongming paddy field were carried out.After the operation of the cyclic regulation and storage wetland,a total of 6239.9-9359.9 m^(3)of irrigation water was saved.
