Analysis on the spatial structure and characteristics of the eminent tourism resources in South Jiangsu - based on GIS

摘要

This paper includes three parts. Firstly, it evaluates tourism resources of South Jiangsu based on the"Chinese tourist resources general survey norm". Then it analyzes the quantity and the spatial characteristics of the eminent tourism resources of south Jiangsu based on GIS. The result of comprehensive evaluation and spatial analysis showed that the humanity tourism resources play fundamental roles in the structure of the eminent tourism resources, and the natural tourism resources are important parts; and in the spatial distribution, the tourism resources show the characteristics of "strap" and "circle", and disequilibrium distribution in region. Secondly, it makes use of the graph theory to analyze the spatial structure of the eminent tourist resources and analyzes the topological properties of the tourism resources network using several indexes such as β, γ indexes, accessibility index , average directory length and the shortest path matrix, etc. In the end, the paper pays attention to the spatial structure of tourism resources -city relations. Non-equilibrium index and geographical relation ratio are used to observe the spatial structure between the eminent tourism resources and the five cities in south Jiangsu.
