Abstract
The living environment in Chinese cities is dominated by blocks of collective housing, and the built environment at the neighborhood scale has become the most important space for urban residents to carry out their daily lives. Especially during the new crown epidemic, high-density, high-aggregation communities have become the focus of urban management and control. At present, China is facing a large number of residential renewal actions. In combination with the impact and thinking of the epidemic, promoting health, maintaining distance and living safety has become an important purpose for the renewal of the built environment of neighbors in the future. This article uses Beijing Dongba Street as a research sample, combined with existing research on epidemic thinking and related health and safety at home and abroad, and analyzes residents' behavior and preferences through questionnaire surveys, individual interviews, and big data collection, and divides residential units -Neighborhood Units-Three Circle Layers of City Blocks. At the same time, combined with the configuration of spatial elements (such as buildings, green spaces, functions, facilities, etc.) of the built environment of different circles, determine the influence weights of the spatial elements of the built environment at different circle scales, and then construct a neighborhood-scale built environment update from the perspective of post-epidemics Design Strategy.
