Evaluation of the supply capacity of livelihood service facilities in the post-epidemic era

Abstract

Livelihood supply security is a critical issue when a public health emergency comes, and the layout planning of existing commercial facilities in China is not yet able to meet the livelihood supply in emergency situations. Evaluating the layout plan of existing commercial facilities is the first step to optimize them. Based on the theory of community living circle , this study takes the central urban area of Hefei City as the scope of research, uses the big data platform and GIS to analyze the accessibility of commercial facilities for people s livelihood supply, conducts comprehensive evaluation at the community level, and explores the development direction of optimizing the planning and layout of commercial facilities for people s livelihood supply in the community living circle. The final analysis concludes that the layout planning of livelihood supply commercial facilities in areas with relatively low degree of construction at the edge of the central city of Hefei is unable to meet the basic living needs of residents under normal conditions. The problem is less obvious in the core area of the central city, but is further magnified in the face of sudden public health events, and its problematic area is more obviously expanded.
