[Research hotspots and trends of urban stormwater management in China based on resilience theory.]

Under the context of frequent flood disasters in China, stormwater management practices such as sponge cities can play a role in flood mitigation and improve the 'resilience' of cities to flood. Resilient city is a concept related with adaptation to disasters, which is increasingly applied to stormwater and flood risk management in some countries. Based on the theory of resilience, we used the scientific metrological analysis tool CiteSpace to review the actualities of Chinese research on rainfall flood, analyzed the hot spots and related technologies of stormwater management from three aspects including ecology, engineering and society of stormwater resilience. Results showed the shortcomings in cross-sectoral stormwater management, and water regulation and storage management of land use at different scales from region to block. We proposed that 'ecology-engineering-society' should be set as the core to establish an adaptive and resilient stormwater management system that offers service to 'region-city-block' with the support of multi-technology integration in the future.
