基于熵权TOPSIS方法与模糊物元模型的河西走廊地区旅游生态安全评估

Tourism ecological security assessment in Hexi Corridor region based on entropy weight TOPSIS method and fuzzy matter-element model

旅游地生态安全评估事关旅游可持续发展,择优选取评价方法对降低旅游生态安全评估结果不确定性意义重大。基于此,以河西走廊地区5个地级市2011—2020年旅游生态安全状况为研究对象,构建旅游生态安全评价指标体系,对熵权-优劣解距离法(熵权TOPSIS法)与模糊物元模型量化结果进行评价。结果表明:(1)2种方法评价结果表明,河西走廊地区旅游生态安全总体呈上升趋势。(2)河西走廊地区驱动力指数与压力指数变化趋势相对协调,影响指数与状态指数变化趋势相似,响应指数较好地反映了区域政府的举措成果。(3)模糊物元模型方法获得的评价结果可信度更高。研究结果可为评估旅游生态安全体系选取模型时提供一定参考。

The assessment of ecological security in tourism destinations is intricately linked to the sustainable development of tourism,and the careful selection of evaluation methods plays a critical role in mitigating uncertainties surrounding the results of such assessments.On the basis of analysis,this study focuses on the tourism ecological safety situations in five prefecture-level cities in the Hexi Corridor region of Gansu Province,China from 2011 to 2020.It constructs a comprehensive index system for evaluating tourism ecological safety and uses the entropy weight TOPSIS method and the fuzzy matter-element model to quantitatively assess the results.(1)The results of both methods suggest that there is a general upward trend in tourism ecological security in the Hexi Corridor region.(2)The trend of change in the driving force and pressure composite indices in the Hexi Corridor region is coordinated,the trend of change in the impact and state composite indices is similar,and the response composite index better reflects the results of regional government initiatives.(3)The evaluation results obtained using the fuzzy matter-element model method have higher credibility.These findings can offer valuable insights for the selection of models to evaluate the ecological safety of tourism systems.
