武汉市商业中心空间特征及影响因素分析

本文以武汉市主城区为研究对象,首先基于手机信令的居民出行OD数据识别商业中心的势力范围和腹地,并分析了研究区商业中心的空间特征;然后构建了影响腹地规模的指标体系;最后通过熵权法对影响因子赋权,计算得到各商业中心的综合水平。研究结果表明:①研究区商业中心呈多核心分布特征,其影响范围沿地铁分布,长江对其具有明显分隔作用;②POI多样性与商业中心腹地规模有较强相关性(0.879 8),商业中心吸引力更多取决于其服务水平和交通发达程度;③汉街和街道口虽为区级商业中心,但由于位置较好、交通便捷,仍是附近居民消费、游憩的首选。

Analysis on the spatial characteristics and influencing factors of Wuhan commercial center

Taking the main urban area of Wuhan as a case, this paper identifies the sphere of influence and hinterland of the commercial center based on the residents' travel OD data of mobile phone signaling, analyzes the spatial characteristics of the commercial center of the study area, constructs the index system that affects the scale of the hinterland, and calculates the comprehensive level of each commercial center by weighting the influence factors by entropy method. The conclusions are as follows:①Wuhan's commercial centers are characterized by multi-core distribution pattern, and the summarize sphere of influence is mainly distributed along the subway, and the Yangtze River plays a clear separation effect on them.②POI diversity has a great correlation with the scale of the commercial center hinterland (0.879 8), and the attractiveness of the commercial center depends more on its service level and traffic development degree than others.③As district-level commercial centers, Hanjie and Jiedaokou are still the first choice for consumption and recreation of nearby residents for their location and convenient transportation.
