面向健康安全高密度城市治理的社区生活圈体检评估

Physical Evaluation of Community-Life Circle for Health, Safety, and High-Density Cities Governance

基于多元城市大数据,提出一套15 min社区生活圈定量化体检评估体系,从生活服务和健康安全两大方面对生活圈进行精细化测度,并以北京、上海、深圳及武汉4座高密度特大城市为案例,进行实证分析。结果表明:综合来看4座城市中上海社区生活圈建设水平最高,4座城市在公共服务设施建设上体现出不同方面的侧重。针对4座城市生活圈存在的问题,提出全面提升设施覆盖率水平、探索差异化发展路径、建立安全连续交通网络、构建社区防控设施嵌套体系等优化建议,为下一步进行规划整合及公共服务质量提升提供重要支撑。

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.
