Abstract: Urbanization has inevitably brought the threat to the urban water ecosystem. Ecological restoration and water environment rehabilitation play the major effect in the urban water system control. The ecological restoration of urban water system has three key elements,including water quality,water quantity and aquatic ecosystems. The important restoration measures consist of wetland building,vegetation planting,riparian ecology governance,and others closely related to urban wetlands. There are some common intersections between urban water system ecological restoration and urban wetland planning,such as goals, approaches,measures and technologies. With the ecology theory as the guiding principle,an urban wetland net can be built to merge with urban water system, urban ecological corridors and green patches on the basis of the existing urban water system resources. Taking the Meishan City of Sichuan province for example,this paper proposes for the urban planning and development of the wetland ecological restoration of the urban water system.
