Identification of the Non-Optimal Tourism Regions in the Three Gorges Area and Its Development Approach
以重庆三峡库区15个区县为案例，通过聚类分析识别出8个非优旅游区，并提出了多中心-腹地旅游发展模式。
Studying the non-optimal tourism regions aims to identify the counties where are relatively weak in the tourism attractions,and( or) lagged in regional tourism development,and further to define the development orientation and promote regional tourism to develop in a coordinated and balanced manner. Choosing the 15 administrative districts in the Three Gorges Reservoir area in Chongqing as cases,this paper carries out hierarchical cluster analysis through SPSS by three variables and they are the abundance degree of tourism attractions,tourism resource quality and resource attractiveness. The cluster analysis and comparisons between classes indicate that the non-optimal tourism regions in the Three Gorges area in Chongqing include 8 counties,covering Yunyang,Kaixian,Fengdu,Shizhu,Fuling,Changshou,Banan and Yubei,mostly located in theprelude section of three gorges The total area of the non-optimal tourism regions accounts for almost half of the study areas. However,both the tourism resources above excellent class and tourism income in the non-optimal tourism regions are far less than those in the advantage regions. The present study suggests that the tourism development model ofMulticenter-hinterland,that is,three geographic clusters around Chongqing,Wanzhou,and Wulong,is suitable for application in the Three Gorges Reservoir Area tourism development. The first cluster focus on developing thematic leisure tourism based on urban customers,the second prioritizes cultural eco-tourism,and the third develops sightseeing and holiday tourism.
