旅游中心地空间外向度及等级体系研究--以全国27个优秀旅游城市为例

采用旅游流强度模型，比较了全国27个主要旅游城市的旅游外向功能量及旅游流强度，并在此基础上运用主成分分析和聚类分析方法，将它们划分为5个等级体系，并对各级旅游中心地进行了评价。研究表明，我国旅游中心地区域发展不平衡，发展态势与我国经济发展态势基本吻合，从发展水平看，沿海高于内陆，东部高于西部，南方高于北方；旅游流强度能较好地刻画旅游中心城市的等级，旅游流强度大的城市，旅游中心地级别愈高，旅游业愈发达，反之亦然。

Study on Spatial Extraversion and Hierarchical System of Tourism Central Place--A Case of 27 Outstanding Tourist Cities

Because the tourist activity needed to rely on the specific urban collecting and distributing flow of tourists,under the strong influence of tourist flow,these cities and towns gradually developed into the travel center in the specific area.These centers were defined as tourism central places concerning the tourism services provided by them,such as transport for the tourists,accommodation,tourism management,tourism information services,and so on.Furthermore,the difference of tourism central places' centricity became more and more evident,as a result,the hierarchies of tourism central places began to come into being,and this was closely related with the spatial connection of tourist flow.So drawing lessons from computing technology that city flow,this article analyzed quantitatively the extraversion of tourism central places by means of intensity of tourist flow.On this basis,the author divided them into five hierarchical systems,and had appraised the tour centers at all levels.It showed: the tourism central place was developed unevenly in China,its developing state and economic developing state of country were identical basically.From the point of development level,it concluded that the coastal land was higherthan the inland,the east was higher than the west,and the south was higher than the north.In addition,the intensity of tourist flow could better depict the hierarchical systems of tourism central places,in other words,the larger intensity of tourist flow,the higher the rank of tourism central place,the more developed tourism industry was,vice versa.
