山西A级以上旅游景区可达性测度研究

Accessibility Analysis of Shanxi Tourist Attractions above Class A

针对传统旅游景区可达性测度模型缺乏实际路网微观通行信息的问题,提出利用互联网地图导航服务功能,借助Python语言构建网络爬虫,批量获取了山西省陆路交通研究单元(格网)分别至A级以上各等级旅游景区通行路径和时间距离,并以全局可达性(平均可达景区时间)和局部可达性(最近可达景区时间)作为旅游景区可达性测度指标,来分别探讨山西省A级以上旅游景区的时空可达性空间分布特征及规律。研究结果表明:1)影响山西省旅游景区可达性的因素主要有旅游景区空间分布以及路网结构特征差异;2)研究单元的全局景区可达性整体水平较优,且具有明显的陆路交通指向性,呈现出条带式的连续分布;3)研究单元的局部景区可达性,呈现出圈层式的不连续分布特点,空间分异特征较为显著。

According to the fact that traditional accessibility calculation methods cannot take into account traffic realistic conditions.Based on internet map navigation service,the paper uses Python language to crawl the realistic traffic path and time in Shanxi province,and uses the average time and shortest time as the accessibility indicators.The spatial and temporal accessibility distribution characteristics of each residential area to tourist attractions above class A in Shanxi province are discussed.The results show that:1)The main factors affecting the accessibility of tourist attractions in Shanxi province are the spatial distribution of tourist attractions and the difference in road network structure;2)The overall level of accessibility of the research unit is relatively good,and it has obvious land traffic directivity and shows a continuous belt-shaped distribution;3)The local level of accessibility of the research unit are significantly different in space,showing a discontinuous circle-layered distribution.
