Abstract: The city greening area, the rivers flowing through the city and the city road green space need to be brought into the overall urban planning and construction in the design and construction of sponge city. A complete water ecosystem with water-circulating, water-retaining and water-proofing functions must be es-tablished to make full use of city rainwater to solve the urban hydrological and ecological environment fun-damentally. This paper discusses the definition, principle and construction strategies of the sponge city, pro-poses specific ways for thorough solution of the hydrological and ecological environment of the sponge city.
