基于POI数据的武汉市多类型商业中心识别与集聚特征分析

Research on the Identification of Multiple Types of Commercial Center and Spatial Patterns in Wuhan Based on POI Data

以武汉市251148条商业POI数据为基础,利用标准差椭圆、核密度分析、最邻近距离分析等方法识别武汉市整体及多类型商业中心,分析各类中心的集聚特征。结果表明:①武汉市整体形成"区域—市—组团"商业中心体系,光谷、武广、中山大道为武汉市商业空间的3大核心区域;②不同类型的商业中心在空间上呈现分异性,特别是居民生活中心和商务办公中心;③中心圈层的各类商业中心具有"沿江、沿主干道"集聚分布的特征,外围拓展圈层的各类商业中心围绕经济产业园区分布,远城区圈层的各类商业中心围绕行政中心进行布局。最后,将上述研究结果与武汉市相关规划进行比较,总结商业中心的现状与规划在等级、数量、空间布局方面的差异与问题。

Based on the 251,148 pieces of commercial POI data from Wuhan, the standard deviation ellipse, kernel density analysis and nearest neighbor distance method are adopted to identify general and multi-type commercial centers. The clustering characteristics of various centers are analyzed, and the spatial patterns of commercial centers are summarized. The results show that:① the "regional-city-group" commercial center system can be found in Wuhan. Guanggu, Wuguang and Zhongshan Avenue are the three core areas of commercial space in Wuhan.② Different types of commercial centers show differentiation in space, especially the residential living center and business center.③ Various types of commercial centers in the central area are "distributed along the river or along the main road", while the peripheral urban area tends to have various commercial centers located around the industrial park, and commercial centers surround the administrative center in suburbs. Finally, the results are compared with the relevant planning of Wuhan, and issues related to level, quantity and spatial layout are summarized.
