宁镇扬地区优良级旅游资源空间结构对比研究

利用Stephen Smith总结和提出的旅游区域研究方法，以2007年江苏省旅游资源普查的数据资料为基础，运用AreGIS空间分析的相关工具，对宁镇扬地区的优良级旅游资源的空间结构作了对比研究。结果显示，扬州、镇江具有较典型的金字塔形旅游资源等级结构；宁镇扬3个城市的优良级旅游资源分布都属于集聚型分布，尤以南京的集聚程度最高。在阐述传统通达度计算方法缺陷的基础上，通过权距离修正和扩大网络范围修正之后的通达度分析结果显示，宁镇扬地区是江苏省旅游交通最为发达的区域，尤以南京的通达程度最高。

Research on Spatial Structure of Eminent Tourism Resources in Ningzhenyang Region

In the way of spatial analysis presented by Stephen Smith,based on the data of investigation of tourism resources in Jiangsu Province in 2007, using the tool of spatial analysis in ArcGIS, the authors did some research on spatial structures of the eminent tourism resources in Ningzhenyang. Yangzhou and Zhenjiang had a typical pyramid - shaped hierarchy. Distribution of eminent tourism resources in Ningzhenyang showed clustering pattern,particularly Nanjing. After presenting the disadvantage of the traditional way, amended by weighted distance and expanding the scope of network,accessibility analysis showed that the traffic of Ningzhenyang was the most developed in Jiangsu Province,particularly Nanjing.
