摘要: 从居民日常生活需求出发,社区生活圈被认为是助力城市向精明增长方向转型的关键抓手和 有效路径。基于POI、道路网、DEM等多源数据,构造基于路网可达的15 分钟社区生活圈模型。 搭建包含7 项一级指标、20 项二级指标的生活圈便利度指标体系,从设施总量、设施有无、设施空 间相关性三个方面开展生活圈便利度评价。选取青岛市东岸城区作为实例研究,结果显示:各类设 施便利度空间集聚特征显著,主要分布在发展成熟的城市建成区;单项设施达标率较高,但7 项设 施全部达标占比很低,设施建设多样性有待提升;按照设施空间相关性分析结果,针对898 个设施 极度缺乏的居民点,应在近期优先考虑设施建设。

Abstract: Given the daily needs of residents, community living circle is considered as a critical foothold and effective path in helping urban smart growth. Based on POI, road network, DEM and other multi-dimensional data, this paper develops a model of the 15-min community living circle available through road network. An indicator system consisting of 7 first-level indicators and 20 second-level indicators are established so as to evaluate the living circle convenience in three aspects: total number of facilities, facilities availability, and spatial correlation of facilities. Taking Dongan District in Qingdao as an example, the results show that the spatial clustering feature of overall convenience of facilities in well- developed urban built- up area is significant. The qualified rate of single facilities is relatively high while the proportion of the situation under which all seven facilities meet the standard is very low, and the diversity of facilities needs to be improved. By analyzing the spatial correlation of facilities, the construction of facilities should be given priority in the near future for the 898 residential areas where facilities are extremely lacking.
