摘要
社区生活圈与居民生活息息相关,是城市基层公共服务设施建设的基本单元,是城市更新的重要抓手。科学划定社区生活圈范围,综合测度其建设水平,为推进社区生活圈建设和实现公共资源高效配置提供理论探索,为地理环境与居民行为关系研究提供新的视角及案例。论文基于生活圈科学划定-建设水平评价的研究思路,通过合并步行规划时空圈和Mapbox时空圈数据探索社区生活圈划定的优化方法,从设施布局、空间可获得性和居民满意度等维度构建生活圈建设水平综合测度指标体系,并以乌鲁木齐市为例,开展实证研究。结果表明:(1)合并步行规划时空圈和Mapbox时空圈数据来划分生活圈范围,可以提升划分结果的时效性和边界准确性。(2)设施布局密度和人均享用量对生活圈建设水平的影响较为显著。(3)乌鲁木齐市15 min步行生活圈平均半径为812.75 m,平均面积为2.10 km~2,老城区建设水平高于新建城区,商服类建设水平高于健康管理、教育、出行类等设施,设施数量不足和布局不均衡是造成差异的主要原因。
Community living circles are closely related to residents’lives,and are the basic units for the construc-tion of urban grassroots public service facilities and an important grip for urban renewal.The scientific delinea-tion of the scope of community living circles and the comprehensive measurement of their construction level pro-vides theoretical exploration for promoting the construction of community living circles,achieving efficient allo-cation of public resources,and providing new perspectives and cases for the study of the relationship between the geographic environment and residents’behavior.Based on the research idea of scientific delineation of the scope of the living circle and evaluation of its level of construction,this study explored the optimization method of com-munity living area delineation by combining the data of walking planning and Mapbox living circles,constructed a comprehensive index system for measuring the construction level of living circles in terms of the layout of facil-ities,spatial accessibility,and residents’satisfaction,among others,and performed empirical research by taking the Urumqi City,Xinjiang,China as an example.The results showed the following:(1)Merging the walking route planning circle and Mapbox living circle to divide the scope of the living circle could improve the timeliness and boundary accuracy of the division results.(2)The density of facilities and access per capita had a more signifi-cant impact on the level of construction of the living circle.(3)The average radius of the 15-min living circle of Urumqi City was 812.75 m,and the average area was 2.10 km2.The construction level of old urban areas was high-er than that of new urban areas,and the construction level of commercial services was higher than that of health management,education,travel,and other facilities.The lack of facilities and layout imbalance were the main rea-sons for the difference.
