Under the guidance of the sponge city theory,this paper took Dongda road engineering in Pingtan comprehensive experimental area as an example. In the process of building,the concept of comprehensive utilization of rainwater in low impact development was used. By using rational design of road cross section and permeable pavement systems,the flooding capacity of road and the city's overall hydrological regulation and storage function was improved,thus easing pressure on urban drainage systems. In addition,by using the recessed green belts and the system of pavement rainwater infiltration,purification,overflow and collection,the water supply,rainwater and drainage system was improved gradually,and the effective utilization and emissions of rainwater was achieved.
