摘要
利用GIS空间分析技术和可达性模型,以武陵山片区为案例区,基于公路交通网络对武陵山片区旅游景点可达性水平和空间格局进行分析。分析得出,区域内景点分布较为分散,空间上"南少北多";高等级公路呈"王"字形分布,公路密度较低。区域内景点平均通行时间处在3.863—8.401h之间,均值为5.386h。景点可达性系数极差为0.845,高于平均值的景点有16个,占34%,景点可达性不均衡分布较显著。可达性空间格局大致呈"核心—外围"的圈层分布,景点自身空间区位、周边景点密度和高等级公路分布对景点可达性格局有重要影响。最后,提出区域旅游空间结构优化的相关策略。
Tourism spatial structure is an important influencing factor for tourism development. Spatial pattern of accessibility of tourism scenic spots is an important content of whole spatial structure. The present paper analyzes network accessibility and spatial pattern of scenic spots in Wuling mountainous area based on road traffic network by methods of GIS spatial analysis and accessibility model. The scenic spots are spatial dispersedly. Density of transport of high degree is relatively low. Average transit time of scenic spot is from 3.863 to 8.401 hours, with 5.386 mean hours. Range of accessibility index is 0.845.There are 16 spots higher than average level, accounted for 34% of total number of 47. Accessibility of scenic spots appeared core-periphery spatial pattern, approximately circle distribution. Spot location, regional spot density and high-grade road are important factor for above spatial pattern of accessibility. Finally this paper puts forward relevant strategies of regional tourism spatial structure optimization.
