摘要
以广州市地铁网络和公路网络数据为基础,运用GIS和SPSS等技术,通过重力度量模型、道路加权核密度模型、地铁站服务指数、最短距离模型来构建广州市综合通达性,并分析了广州市中心区和周边区综合通达性的空间特征。研究表明:广州市的综合通达性呈现多中心分布;中心区受历史、自然和经济等因素影响,交通网络发育成熟,高值中心位于越秀区和天河区西部,通达性较好,与区域内人口和经济的相关性不高;周边区交通网络发育不完善,表现出以区政府为中心的空间结构,通达性较差,与区域内人口和经济相关性较高。
This paper uses GIS and SPSS technology to establish comprehensive accessibility of Guangzhou with gravity model, road weighted kernel density, subway station service index and minimum distance metric model based on Guangzhou subway network and road network to analyze spatial characteristics of comprehensive accessibility in central regions and peripheral regions. The results show that accessibility of Guangzhou presents multi-center distribution. As a result of history, natural environment and economic factors, central regions＇ transportation network is at a higher level and the center of the accessibility is located in Yuexiu district and west of Tianhe district. Moreover correlation between population, economy and central regions＇ accessibility is low. However, peripheral regions＇ accessibility is poor and each district government is the center of the accessibility. What＇more, population, economy and peripheral regions＇ accessibility is correlated well.
