基于GIS的池州市城区道路通达性研究

A study of comprehensive accessibility of road network in Chizhou City based on GIS

利用GIS空间分析技术,以池州市城区道路交通网络数据为数据基础,选取道路密度、道路服务指数和路网连接度3个指标,构建池州市交通网络通达性模型,并在此基础上,对池州市城区道路网络的通达性现状进行分析。研究结果表明,池州市城区道路交通网络通达性呈现明显的空间分布,受空间分布格局的影响,商业中心、旅游景点和部分学校周围的通达性较好,研究结果对池州市城区道路网络的优化和扩展有一定指导作用。

This paper,taking Chizhou City transportation network data as the data base,uses a GIS spatial analysis techniques,chooses road density,road service index and the road network connectivity of three indicators,and builds the model of Chizhou City transportation network accessibility.On this basis,it analyzes the Chizhou City transportation network accessibility status quo.The result shows that,Chizhou City road network accessibility shows significant spatial variation,the influence of the spatial distribution of commercial centers,tourist attractions,and some schools around.The result of this study in Chizhou City road network optimization and expansion can provide a scientific reference for urban construction and spatial development.
