摘 要:在我国城镇化的下半场,以人为本、存量规划和集约发展成为当下城市的主旋律,作为承载城市记忆的老城区社区生活圈亟待更新优化。以宜宾市老城组团为例,采用连锁网络模型和基于真实路网的设施可达性分析等方法,结合10大类公服设施POI数据、当地居民对设施的重要性评价数据,对研究区域进行了10分钟社区生活圈的测度探索,并在测度结果的基础上,以生活圈为视角提出了相应公服设施的优化及择址建议。研究结果表明:第一,宜宾老城共可划定出4个10分钟社区生活圈,平均用地规模较小于平原、省会、特大型城市;第二,4个生活圈整体都存在公园广场、社会福利、科教文化这3类设施数量较为欠缺及覆盖范围较小的共性问题;第三,各生活圈生活便利度差异明显,发展不均衡。未来宜侧重优化过渡区、边缘生活圈欠缺设施;第四,基于设施覆盖率及居民可达程度考虑,每个生活圈宜提供中心度前三的地块中心点作为10分钟层级设施的推荐设置点。In the second half of China’s urbanization,people-oriented,stock planning,and intensive development have become the main themes of the city nowadays.The community life circle in the old city,which carries the memory of the city,is in urgent need of renewal and optimization.This study takes the Yibin old city cluster as an example.Using methods such as the Interlocking Network Model and the facilities accessibility analysis based on the real road network,combined with the POI data of 10 major types of public service facilities and data on the importance evaluation of the facilities by residents,it explores the measurement of 10-minute community life circle in the study area.Based on the measurement results,the optimization and site selection of corresponding public service facilities are proposed from the perspective of the life circle.The paper first explains the reasons why Yibin old city cluster is chosen as the study area and why the 10-minute community life circle is taken as the measurement scale of the study.According to the previous literature research experience,the grid of 250 m*250 m is selected as the basic unit for dividing the life circle.The data sources for this study mainly include the vector data of buildings and roads captured by Python on the Baidu and AMAP map platform,and the questionnaire data surveyed and collated in the field investigation,which can be used to judge the impact of various facilities on residents.Based on the Interlocking Network Model and the current domestic 10-minute life circle scale control documents,the above data are used to determine the closeness of the relationship between the grids in the study area and to delineate the scope of the community life circle.As a result,Yibin old city cluster is divided into 4 life circles:central life circle,sub-central life circle,transition area life circle,and edge life circle,with the accuracy of the division results verified.According to the current situation of each life circle,suggestions on the optimization and location sel
