面向健康安全高密度城市治理的小区生活圈体检评估

This paper proposes a quantitative physical evaluation system for 15-minute community-life circles based on multi-source urban big data. Measurements from both life service and health safety were conducted. Taking the four high-density mega-cities, i.e., Beijing, Shanghai, Shenzhen and Wuhan as representative cases, surveys and interviews were performed, followed by empirical analyses. The results demonstrated that the four cities have different emphases on the construction of public service facilities, in which Shanghai has the highest level of community-life circle construction. Aimed at solving the problem of community-life circles within the four cities, optimization suggestions such as comprehensively improving facility coverage, exploring differentiated development paths, establishing safe and continuous transportation networks, and constructing a nested system of community prevention and control facilities were proposed, which may provide important support for further planning integration and improvement of public service quality in high-density cities.
