In the context of disaster normalization, the concept of “resilience” has been gradually introduced into the field of disaster prevention and mitigation in urban communities. In order to resist the increasingly frequent disasters caused by extreme weather, it is necessary to shift the focus of building resilient urban communities to the level of stormwater management. Community resilience is a disaster prevention and mitigation capability based on community resources. In order to solve the deficiency of storm and flood management in the current construction of resilient communities in China, it is necessary to establish a quantitative evaluation system to evaluate it. This paper uses the analytic hierarchy process and Delphi method to establish a community resilience evaluation system from the perspectives of community material space level, community management level and individual level. Then three communities in Hefei City, Anhui Province are selected for practical application of the system, and corresponding optimization and transformation strategies are proposed. The results show that: (1) The resilience of community stormwater management is closely related to the integrated environment of the community, the allocation of flood control facilities and the daily disaster prevention and mitigation management; (2) The ability of disaster prevention and mitigation and the awareness of public participation of the residents in all communities are relatively weak, and the communities invest less in the popularization of stormwater management wisdom; and (3) Resilient communities should not only pay attention to the construction of non-engineering disaster prevention measures, but also to the application of small-scale green infrastructure oriented toward stormwater management.

During the long-term construction and development process of eliminating water disasters and promoting water conservancy in traditional settlements, a set of mature strategies that have simple ecological wisdom in water layout have been formed by adapting to the natural water environment and utilizing the regional water system. This study conducted a qualitative and quantitative analysis of the water layout strategies and their effects on Liukeng Village from three aspects: deciphering the water systematic pattern, calculating the spatial characteristics and quantifying the water environment, to explore the technical assistance and potential of water layout research in traditional rural settlements. The results indicated that Liukeng has an unambiguously systematic water layout pattern of source diversion, middle drainage and end purification of the water. Through 3D point cloud computing, it was shown that the site selection made accurate use of micro-topography and adopted the strategy of a multi-source water management. It formed an organic water system pattern, which provided sufficient water sources for all kinds of needs of Liukeng Village.The Dragon Lake in Liukeng held 83.0% of the precipitation, and the vegetation area accounted for 34.7% of the total area of Liukeng, which had high surface permeability and good middle drainage effects. Water detection showed that the Dragon Lake provided good water quality and purification. The purposes of this study are to fill the gap in previous non-quantitative research on water layout in traditional rural settlements, excavate the hidden information and value of settlements, and deepen our understanding of the ecological wisdom of the overall planning, layout and construction of water conservancy in traditional rural settlements. This knowledge can assist the win-win situation of water conservancy cultural heritage protection and modern utilization. It also provides useful inspiration and reference for properly dealing with the problems of rain and flooding, realizing the sustainability of water resources, and protecting the ecological environment in the process of the development and construction of village settlements in China.
