Reconsidering the Suitability Assessment Method for Glacier Tourism: A Case Study from Tibet, China

Glacier retreat is becoming more widespread and severe due to global warming, and improper exploitation of glacier resources by tourism activities accelerates the destruction of glacier landscapes. Therefore, establishing a set of quantitative assessment tools is critical for guiding the rational utilization of glacier tourism resources. This study selected regional tourism resources, the natural environment of glaciers, service support, and market demand factors to build a suitability assessment method for glacier tourism (SAMGT), and it used the Delphi and Analytic Hierarchy Process (AHP) to determine the index weights, and combined them with GIS analysis technology. The Tibet autonomous region was proposed in this study as a case to build the SAMGT and provide scientific support for the rational development, scientific management, and sustainable development of glacier tourism resources. With regard to influencing the suitability of glacier tourism resource development, the results indicate that the weights of glacier resource endowment, ecological vulnerability, and tourism resource combination were high whereas that of market demand-related factors was low. The glacier tourism resource development area in Tibet can be divided into suitable, relatively suitable, barely suitable, and unsuitable exploitation zones, accounting for 5.39%, 9.76%, 15.28%, and 69.57% of the total area, respectively. Five representative glaciers were selected to verify the validity or test the rationality of SAMGT and prove that the model is reasonable, innovative, and effective from the perspectives of multiple dimensions and the comprehensiveness of the selected indicators.
