摘要
利用GIS手段,以重力度量模型、网络连通度和最短距离度量模型为基础,构建综合评价指标分析了广佛都市圈17个县区、127个空间节点的公路路网通达性。研究表明:广佛都市圈的公路路网发育较成熟,受自然环境、经济及空间距离等因素的影响,其通达性空间格局呈明显的圈层结构,通达性从都市圈的几何中心向外围递减,且向东—西方向延伸,成走廊态势,南北向的通达性递减趋势明显快于东西向,珠江北岸通达性优于南岸,并对广佛都市圈交通基础设施的规划提出调整建议。
By using GIS tools,based on gravity models,network connectivity and minimum distance metric model,build a comprehensive evaluation index to analyze the road network accessibility of Guangzhou-Foshan metropolitan area.It is found out that as a result of the natural environment,economic and spatial distance and other factors,the accessibility of Guangzhou-Foshan metropolitan area shows an obvious grade-layer structure and core-periphery structure.Extending from west to east,the accessibility decreases from the geometric center to the periphery.And the accessibility in north side of Pearl River is better than the south side.Finally this paper provides some advice to the transportation planning of Guangzhou-Foshan metropolitan area.
