Abstract

The sponge landscape design was carried out in a middle school of Nanchang which was taken as an example, and then the benefits of sponge city after reconstruction was analyzed. The spongy bodies are excavated and a perfect rainwater system is formed based on the current conditions, according which rainwater can be effectively infiltrated, stored, purified and recycled. The original impervious concrete pavement, mud and fish pond of the plot have been designed and transformed into pervious pavement, lawn and pond, and the runoff per unit area increased from 0 m, 0.24 m and 0.56 m to 0.15 m, 1.08m and 0.7 m. Finally the capacity of runoff control in the design unit area of the site after reconstruction is far greater than that in the original area, and is also far higher than the requirements of runoff control in Nanchang under the background of sponge city construction, thus forming a good sponge city benefit.
