社区生活圈划分及建设水平综合测度方法OA北大核心CSTPCD

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.
