With the acceleration of global climate change and urbanization, many large and medium-sized cities in China have been frequently subjected to heavy rains and floods. Thus, the question of how to reduce the impact of floods and achieve rapid recovery has attracted much attention. We use the urban community as the basic unit to examine the living environment, internal facilities, and surrounding environment characteristics of six different types of communities in the Jianye District of Nanjing City. First, we use factor analysis and the binary logistic regression model to analyze pre-disaster preparation, disaster response, and post-disaster recovery. Second, we analyze the resilience of the community at different stages. Then, we explore the influencing factors of the built environment on the resilience of the community. Results show that the built-up environmental factors, such as topography, riverfront, building coverage ratio, green space rate, and land use diversity, have a significant impact on community resilience. Finally, we proposed several suggestions for improving the flood resilience of Nanjing City.Sustainability 2020, 12, 2401 2 of 16 of drainage systems [22]. Distance to the coast or public service facilities will also affect the perceptions of urban residents about their vulnerability to flood [23]. Given that the relationship between the built environment and disaster has been confirmed [4,24], preventive measures, such as construction of dams, serve to reduce vulnerability to flooding.Community resilience is an increasingly employed perspective to understand and cope with disaters [25]. Although built environment remains a fundamental aspect of this resilience, its relationship with social structure is emphasized in this framework. In the context of this research, community resilience refers to strategies and actions taken to respond to actual urban flooding. From this perspective, Kim and Hastak [26] regard the built environment as the space to construct social networks. They believe that different types of built environments create different levels of social networks. Residential segregation gathers vulnerable groups in specific spaces; hence, social vulnerability has become increasingly important in disaster prevention and management [27][28][29][30]. As an important part of a green infrastructure, green space plays a role in reducing the impact of climate change on the development of human society [31][32][33]. Given this role, developed countries are more inclined to social prevention of flooding than engineering flood control, such as improving property, disaster prevention, and design and planning of urban flood control [15,21,24,[34][35][36][37][38][39], as discussed by Lang et al [35]. Thus, the objective of urban planners is to improve the built environment, which is conducive to constructing a flexible community before disasters take place.Community resilience to flooding disasters and the role of the built environment have been evaluated in different countries [40,41]. However, seve...
