集中连片特困区旅游经济空间网络结构演化 ——以武陵山片区为例

以2010年、2013年、2016年和2019年为时间截面,运用修正引力模型和社会网络分析法,结合ArcGIS空间分析工具,以武陵山片区42个国家级贫困县为标靶,研究其旅游经济网络密度、中心性、核心-边缘结构并运用E-I派系指数探讨行政隶属关系对区域旅游经济网络的影响。结果表明:武陵山片区旅游经济联系强度不断增强,但呈显著的空间差异,恩施市、黔江区、武隆区和新化县等县市间旅游经济联系强度居于高值区;武陵山片区各县市度数中心度、接近中心度、中间中心度区间差值敛缩态势显著,旅游经济联系日趋便利化,旅游经济联系网络趋于均衡;E-I派系结构表明受行政隶属关系影响,其核心区覆盖范围不断拓展,行政隶属关系对区域旅游经济联系的负向影响趋于弱化,湖北省、湖南省、贵州省、重庆市4个子群(派系)间的旅游经济开放程度稳步提升但仍有较大改进空间。

Structure and Evolution of Tourism Economic Space Network in Contiguous Destitute Areas:A Case Study of Wuling Mountain Areas

Applying the improved gravitational model,social network analysis(SNA)and ArcGIS spatial analysis,this paper analyses the structure and evolution characteristics of the tourism economy network in 42 national-level poor counties in the Wuling Mountain Areas,with 2010,2013,2016 and 2019 as the research time section.The result shows that the intensity of tourism economic linkages in the Wuling Mountain Areas is increasing,but there is a significant spatial difference.The intensity of tourism economic relations between counties and cities such as Enshi City,Qijiang District,Wulong County and Xinhua County is in the high value area.The concentration of centrality,near centrality,and intermediate centrality of each county in the special poverty-stricken areas are significant in the Wuling Mountain Areas.The tourism economic ties are becoming more convenient,and the tourism economic network tends to be balanced;The analysis of E-I index shows the coverage of its core area has been continuously expanded.The negative impact of administrative affiliation on regional tourism economic linkages has weakened.The tourism economy between the four subgroups(sects)of Hubei Province,Hunan Province,Guizhou Province and Chongqing City has increased steadily,but there is a lot of room for improvement.
