摘要
基于武汉市主城区公共文化设施POI数据、居住小区数据、公交站点数据以及道路网络矢量数据,利用ArcGIS软件的网络分析方法计算公共文化设施可达性,借助GeoDa平台,通过Moran's Ⅰ指数探究公共文化设施可达性的空间分异特征.结果表明:居住小区和公共文化设施的公交配给和服务能力均较好,公交出行十分便捷;公共文化设施可达性整体较好,其空间特征为圈层式由中心向四周递减;公共文化设施供给均等化水平较高,可达性空间分布由中心高值集聚区逐渐向四周低值集聚区过渡.
Abstract
Based on the POI data,residential district data,bus stop data and road network vector data of public cultural facilities in the main urban area of Wuhan,this paper uses the network analysis method of ArcGIS software to calculate the accessibility of public cultural facilities,and explores the spatial differentiation characteristics of the accessibility of public cultural facilities by Moran's Ⅰ in-dex with the help of GeoDa platform.The results show that:the public transportation distribution and service capacity of residential communities and public cultural facilities are good,and public transportation is very convenient.The accessibility of public cultural fa-cilities in the study area is generally good,and its spatial characteristics are circled and decreasing from the center to the periphery.The level of equalization of the supply of public cultural facilities is high,and the spatial distribution of accessibility gradually transi-tions from central high-value agglomerations to low-value agglomerations.
