基于适宜性分析的沙漠旅游主体功能区划——以宁夏中卫市沙坡头区为例

Principal Function Regionalization of Desert Tourism based on Suitability Analysis: A case study in Shapotou, Ningxia, China

基于ArcGIS和YaAHP评价法,从沙丘相对高度、坡度、日平均气温≥10℃持续时间、与水体距离、与沙漠距离和与居民点(公路)距离等方面评价宁夏中卫市沙坡头区沙漠旅游适宜性,并结合土地利用现状对沙坡头区进行沙漠旅游主体功能区划。结果表明:研究区沙漠旅游适宜性可分为5类区域,即高、较高、中、较低和低适宜性区域;研究区沙漠旅游主体功能区划分为沙漠旅游开发区、沙漠旅游适度开发区、沙漠旅游不适宜开发区和沙漠旅游限制区。根据功能区划,提出了相应的调控措施,以期为宁夏中卫市沙漠旅游的合理开发提供一定的参考。

Based on ArcGIS and YaAHP evaluation method, desert tourism suitability in Shapotou District of Zhongwei, Ningxia was evaluated by six indicators, just dune height, slope, suitalble days, the distance from water area, the distance from desert and the distance from city/road. And function regionalization of desert tourism in Shapotou District was given based on desert tourism suitability evaluation result and land use data. The results show that the desert tourism suitability in Shapotou District can be divided into five suitability regions, namely, high, relatively high, medium, relatively low and low, and functional region of desert tourism in Shapotou District is divided into desert tourism development zone, desert tourism restrict- ed development area, desert tourism inadequate development zone and the desert tourism restricted area. Finally, according to the functional regionalization, we put forward corresponding development and manage- ment measures.
