西南地区入境旅游时空差异演变分析

以西南五省市区1997—2011年旅游外汇收入为基础，运用区域经济发展差异衡量相关指标并结合GIS空间分析方法对西南地区入境旅游进行时空差异演变分析，结果发现：（1）西南地区入境旅游发展总体不均衡，绝对差异不断扩大，相对差异在波动中缩小；（2）西南地区入境旅游经济空间极化现象显著，区域旅游经济规模呈首位型分布；（3）西南地区入境旅游发展潜力巨大；（4）影响西南地区入境旅游时空差异的主要因素包括旅游资源、区位交通通达性和经济发展水平。

Analysis on the Space-time Difference Evolution of the Inbound Tourism in Southwestern China

Based on the revenue from inbound tourism of the five provinces in Southwest China, the evolution of space-time difference characteristics of inbound tourism in Southwest China was analyzed by using some indexes of different regional economic development and combing GIS spatial analysis. The research shows that inbound tourism development is in general unbalanced in Southwest China. Absolute difference is rising while relative difference is narrowing in volatility, and the spatial difference is quite significant. Spatial polarization characteristics exist and spatial agglomeration shows the tendency of decrease. To explore the mechanism of time and space difference, rank-size distribution theory is used, and the result indicates that inbound tourism in Southwest China is first-place distribution. Finally tourism resources, economic development and traffic conditions influence the space-time difference of the inbound tourism of Southwest China.
