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 6.239.9-9.359.9 m3 of irrigation water was saved.
