Evaluation on Tourism Suitability in Loess Plateau Based on RS and GIS:a Case Study on ZhongYang County, Shanxi Province

摘要

Evaluation on tourism suitability is one of the hot problems in tourism research recently, which is based on survey of tourism resources and ecological environment. It makes estimation and decision on specific area whether it is suitable for tourism development, then confirms optimum area, preferable area, general area and inferior area. This paper take Loess plateau, a typically area with fragile environment in China as research area, built some indicators and a model of tourism suitability. Evaluation indicators included: terrain, slope, vegetation, waterbody, tourism resources and loess landform. From RS image, authors picked up indexes information such as vegetation, waterbody, tourism resources and loess physiognomy. From DEM, terrain and slope information were extracted. By spatial and buffer analysis of GIS, this paper realized quantitative evaluation and spatial continuity of tourism suitability. Finally, the authors took Zhongyang county in Shanxi province as a case study, analyzed tourism suitability in this county and educed the optimum area, preferable area, general area and inferior area of tourism development. Nanchuan river valley in Zhongyang is the optimum area, it can develop summer resort, forest vacation, cave adventure and folk experiencing. In the west of Zhongyang, some typical loess physiognomy distributed. Wujiamao loess landscape is preferable area. When developing tourism, environment protection and watering should be solved firstly. In some general and inferior areas, tourism development is prohibited in a short term. Furthermore, the paper brought forward the plans on tourism and some problems should be noticed in Zhongyang county.
