基于GIS网络分析的汉中市旅游交通路网的空间结构特征

Spatial Structure Features of Tourism Traffic Network in Hanzhong City Based on GIS Network Analysis

交通路网空间结构是区域旅游发展的重要保障,关系着交通、旅游业和城乡统筹发展。为了评估秦巴山区的旅游交通路网的发展水平,文中以陕西省汉中市为例,选择114个景点、基础交通路网和旅客出行数据,借助GIS(Geographical Information System)网络分析和在线地图服务,考虑时间、距离成本等约束条件下的游客出行成本和路线规划,并从路网连接性和可达性的视角探讨汉中市旅游交通路网的空间结构特征。结果表明:汉中盆地的路网连接性良好,汉台区、南郑区、勉县的旅游交通路网的可达时间在30 min~60 min,出行距离小于30 km;秦岭南麓、巴山北麓山区地形复杂,镇巴县、西乡县、洋县的景点出行距离和时间成本较高,旅游交通路网的连接性较差,出行距离成本大于50 km,不适宜规划短期旅游路线。

The spatial structure of the traffic road network is an important guarantee for the development of regional tourism,which is related to the overall development of transportation,tourism and urban and rural areas.In order to evaluate the development level of tourism traffic network in Qinba mountain region,both the 114 scenic spots,basic traffic network and passenger travel data of Hanzhong City,Shaanxi Province,are employed to consider tourist travel cost and route planning under constraints such as time and distance cost with the help of GIS network analysis and online map service.From the perspective of network connectivity and accessibility,this paper presents the spatial structure characteristics of tourism traffic network in Hanzhong City.The results show that traffic network connectivity of Hanzhong basin is well connected.The reachability time of tourism traffic network in Hantai District,Nanzheng District and Mianxian county is within 30-60 minutes and the travel distance is less than 30 km;The terrain at the southern foot of Qinling Mountain and the northern foot of Bashan mountain is complex.The travel distance and time cost of scenic spots in Zhenba County,Xixiang County and Yang county are relatively high,the connectivity of tourism traffic network is poor,and the travel distance cost is greater than 50 km,so it is not suitable to plan short-term tourism routes.
