Since constructing the first batch of pilot projects of sponge city in China in April 2015, Xi'an government has vigorously promoted the construction and development of sponge city in Xixian new district, which has become a model of sponge city construction in China. In recent years, although the construction of sponge city in Nanchang has made little achievements, there are still some problems, such as the lack of rain and sewage diversion in the drainage pipe network system, the lack of professional and technical talents and technical support in the construction of sponge City, and the lack of public awareness of participation in the construction of sponge city. Nanchang can fully learn from the advanced construction and management experience of Xixian new area, establish an independent sponge city construction management department, carry out the upgrading and reconstruction project of drainage system, strengthen the professional knowledge training and technical support for sponge city construction personnel, conduct the knowledge publicity and implementation of "sponge city construction", and advocate the whole people to participate in the construction of sponge city, for the sake of pushing the sponge city construction in Nanchang to a new level.
