基于公路交通网的旅游景区时间可达性分析——以武汉市为例

Analysis of Accessibility Time of Tourist Attractions in Wuhan City

基于武汉市实际的公路交通网,利用Arc GIS空间分析工具和可达性模型,参考武汉市公路网结构,定量分析了武汉旅游景点的可达性及其空间格局。结果表明：景点分布空间上呈现出＂大分散,小集中＂的特点;武汉市旅游景区可达性呈现由中心向周边递减的圈层分布;区域内景点平均通行时间在0.723 8~3.003 5 h之间,景点可达性系数极差为1.766 6;受旅游景点空间分布、公路网结构及景点知名度的影响,旅游景区可达性空间格局不平衡分布较显著。最后,提出武汉市旅游空间结构优化的相关策略。

The present paper quantitatively analyzes network accessibility and spatial pattern of scenic spots in Wuhan based on road traffic network of Wuhan by methods of GIS spatial analysis and accessibility model.The network accessibility of scenic spots in Wuhan appeared decrease progressively from core to periphery,approximately circle distribution.Average transit time of scenic spot is from 0.723 8 to 3.003 5 hours.Range of accessibility index is 1.766 6.Affected by the spots location,road traffic network and popularity,the spatial pattern of accessibility of scenic spots are significant non-equilibrium distribution.Finally this paper puts forward relevant strategies of regional tourism spatial structure optimization.
