Abstract: After more than four years of innovative practice in 30 sponge city pilot areas across China, the urban ecological environment had been improved significantly, and the pilot results had been remarkable. On the basis of summarizing the pilot experiences, in order to further implement the goals and requirements of the Guiding Opinions on Promoting the Construction of Sponge City issued by the General Office of the State Council, the Ministry of Housing and Urban-Rural Development clearly puts forward the need for "systematic and full-field promotion of sponge city construction" at the 2020 annual National Work Meeting. Based on the research and practice of systematic and full-field promotion of sponge city construction in Shanghai, especially the experience of Lin-gang pilot area, this paper studied from the aspects of system construction, full-field promotion, and promotion of Lin-gang after the pilot, so as to provide reference for the systematic and full-field promotion of sponge city construction in other cities.
