中文摘要：

文章构建了入境游客转移数量模型、入境旅游流空间集中指数模型、入境旅游流转移态矩阵,基于1994～2008年入境旅游统计数据和入境游客抽样调查数据,定量测评陕西、四川、云南三省入境旅游流集聚指数与扩散指数、入境旅游流集聚态指数与扩散态指数;通过时间序列对比,揭示西部三省入境旅游流的空间集散特征与动态变化过程;通过西部三省之间的对比,分析其入境旅游流空间集散的地域差异性。研究表明：四川省入境旅游客流集散能力最强,云南省居中,陕西省最弱;中国入境旅游客流系统是一个＂东部引领西部,西部反作用于东部＂的时空地域格局复杂的动态平衡系统。文章结合历时性分析方法和共时性分析方法,选取西部三省开展入境旅游客流集散时空动态研究,旨在为探索中国西部入境旅游客流集散的时空演变特征与潜在机理提供典型案例。

英文摘要：

Based on models such as transfer-quantity of inbound tourists,spatial concentrated index and transfer matrix of inbound tourist flows,with statistical data of inbound tourism and sampling information of inbound tourists from 1994 to 2008 provided by National Tourism Administration of China,the paper quantitatively evaluates the spatial concentrated index and spatial diffused index of inbound tourist flows in Sahanxi,Sichuan and Yunnan Provinces.Through the comparison of spatial series,the spatial concentrated characteristics and the process of dynamic changes are revealed in the inbound tourist flows of three provinces in western regions.Through horizontal comparison of the three provinces,regional disparity of spatial concentration of inbound tourist flows is analyzed.The study indicates that in terms of the concentration and diffusion of inbound tourist flows,Sichuan province enjoys strongest capability,followed by Yunnan province,whereas Shaanxi province is the weakest.China＇s inbound tourist flow system is a regional complex dynamic balance system in which ＂eastern regions lead western regions,while western regions react eastern regions＂.This study selects three provinces in western regions in the hope of providing a typical case study for the exploration of the characteristics of spatial and temporal changes of the concentration and diffusion of inbound tourist flows in China＇s western regions and potential mechanism.
