湘西地区交通可达性对旅游环境系统韧性的影响及空间溢出效应

Impact of traffic accessibility on the resilience of tourism environment system and spatial spillover effects in Xiangxi Area

运用集对分析、加权平均旅行时间和综合评价分析等方法,研究湘西地区2000—2020年旅游环境系统韧性和交通可达性演化特征,并利用空间杜宾模型揭示交通可达性对旅游环境系统韧性的空间溢出效应。结果表明:(1)旅游环境系统韧性均值随着时间的推移呈现显著上升的态势,空间分布上南部变化相对稳定,而中部和北部变动明显;基于旅游环境子系统韧性的测算结果,将各区县划分为高高高、高低低、高低高、低高高、低低高、低低低6种类型。(2)交通可达性呈现显著的“核心-边缘”空间分布结构,形成吉首-凤凰-鹤城-芷江-洪江-中方为可达性高值区的相对优势带。(3)交通可达性提升通过直接作用旅游经济和社会环境系统韧性,并对旅游经济环境系统韧性产生正向空间溢出,进而促进整体旅游环境系统韧性提升。

This study firstly constructs a conceptual model of tourism environmental system resilience and a theoretical framework of the influence of traffic accessibility on tourism environmental system resilience.Then,we take 24 county-level units in Xiangxi Area as the study area,introduce set-pair analysis method,weighted average travel time and comprehensive evaluation analysis to research tourism environmental system resilience(TESR).In addition,this research adopts spatial panel Durbin model to examine the spatial spillover effect of traffic accessibility on the resilience of tourism environment system.It is revealed by the results that:1)The mean value of TESR in Xiangxi Area has increased from 0.407 in 2000 to 0.624 in 2020,and the spatial distribution was relatively stable in the south,while the central and northern parts changed significantly.Based on the results of TESR subsystem measurement in Xiangxi Area,the districts and counties were classified into six types:high-high,high-low,high-low,low-high,low-low,low-low,and low-low;2)The traffic accessibility shows the characteristic of decreasing from the central part to the surrounding area,forming the relative advantageous zone of Jishou-Fenghuang-Hecheng-Zhijiang-Hongjiang as the high value area of accessibility,and the development trend of regional traffic integration is prominent;3)The traffic accessibility improves the tourism economic system resilience and tourism social system resilience,which in turn promotes the improvement of TESR.
