中文摘要：

基于场强模型,通过空间分析和聚类分析,利用SPSS19.0和ArcGIS9.3对陕西省10个城市2001-2011年的旅游经济辐射场强进行分析。结果表明：11年间10个城市旅游经济实力和旅游经济辐射场强均有大幅度增强;空间分布整体趋势为中间高四周低;旅游经济辐射场强重心向北偏西发生了一定的偏移,说明旅游经济发展速度有一定区域差异;通过分析发现陕西省已形成了以省会城市为中心城市,其余9个城市为外围城市而构成分工不同的单核地旅游网络空间协作发展格局。

英文摘要：

We analyzed the radiation field strength of urban tourism economic in Shaanxi province from 2001 to 2011 based on field model, Cluster analysis and spatial analysis by SPSS19.0 and ArcGIS9.3. The results showed that the radiation field strength of tourism economic and tourism economy had greatly enhanced and the absolute difference was widening. The field strength middle was higher than the surrounding area in Shaanxi province. The center of the radiation field strength of urban tourism economic had significant offset to north - west and indicating there were some regional differences in the rate of tourism economic development. The polari- zation phenomenon was very apparent. Then we found that the pattern of tourism economic radiation field strength was of ＂the capital city for core city, nine cities for peripheral city＂ in Shaanxi province, they were the different divisions and cooperation for the whole development.
