基于RS、GIS的黄土高原环境脆弱区生态旅游适宜度评价——以山西省中阳县为例

Evaluation on ecotourism suitability in frangile environment of loess plateau based on RS and GIS-exampled on Zhongyang county,Shanxi province

生态旅游适宜度评价为黄土高原环境脆弱区旅游开发提供产品开发、项目选址、旅游分区等方面的决策依据,从而有效降低旅游活动对环境的影响。根据黄土高原区域特征及生态旅游资源的特点,论文构建了黄土高原生态旅游适宜度评价因子和模型。并基于RS、GIS空间信息技术,实现了地形、植被、黄土地貌等6个评价因子的信息采集与评价结果的空间显示,提出了黄土高原生态旅游适宜度评价方法。以山西省中阳县为例进行了实证研究,得到了南川河河谷为该县生态旅游最适宜区、吴家峁黄土地貌等为中适宜区以及一般适宜区和不适宜区。根据评价结果,论文最后提出了该县生态旅游的开发方向及应注意的问题。

Evaluation on ecotourism suitability is a key to tourism exploitation in loess plateau with fragile environment, which can provide references for eeotourism planning, choosing places, products programming. Consequently, it can reduce the bad impacts on environment effectively. According to the characteristic of ecotourism resources in loess plateau, this paper built some evaluation indexes and model of ecotourism suitability. By RS image, the author picked up indexes information, such as terrain, vegetation and loess physiognomy. Using spatial and buffer analysis methods of GIS, this paper realized quantative evaluation and spatial continuity of ecotourism suitability. Thereby, the author put forward a method in ecotourism suitability evaluation in loess plateau, Finally, taking Zhongyang county in Shanxi province as a case study, they analyzed ecotourism suitability in this county and educed the optimum area, preferable area, medium area and inferior area of ecotourism. Furthermore, the paper brought forward the plans on ecotourism and some problems should be noticed.
