Abstract

At present, economic development has become a dominant factor in the promotion of urban renewal in China. This means that decision-makers often overlook the impact of the natural environment on the urban renewal of the region. This paper begins with a review of the literature concerning urban renewal and natural disaster vulnerability in order to discuss the mechanism of interaction between natural disasters and urban renewal. Then, an evaluation model of natural disaster vulnerability in urban areas is constructed, and a DEA model is used to assess the vulnerability of natural disasters in various regions of a city. Finally, using the idea of regional planning, this paper puts forward a method for urban renewal, taking natural disaster factors into consideration, and provides an important direction for urban renewal in order to realize the sustainable development of cities. The findings of this paper substantiate the phenomenon that, at this stage, urban renewal has brought many problems. Although urban renewal enhances the city’s resilience to natural disasters, understanding how to assess the vulnerability of natural disasters in all regions of the city has been a challenge and should be part of an integrated planning approach. This paper puts forward the countermeasure of urban renewal against the background of natural disaster, from the perspective of sustainable development.
