基于云重心理论的山地景区旅游安全风险评估研究

A Study on Risk Assessment of Tourism Security in Mountain Scenic Spots from the Perspective of Cloud Focus Theory

针对旅游安全评价易受主观因素影响,评价指标、权重和安全等级难以确定等问题,在实地调研的基础上,提出从旅游安全信息及获取手段的视角建立评价指标体系,利用公式法确定权重,云重心理论建立评估模型的方法,减少了评估过程中的主观性、不确定性和模糊性,使评估结果更趋于客观、可信。实例说明评价结果与实际相符,验证了本评估模型的正确性。研究成果为景区旅游安全风险评估提供参考。

According to the fact that the evaluation of tourism security is easily influenced by subjective factors,and a series of issues,including evaluation index,weight and safety grade and so on,are difficult to determine,it is necessary to have a field investigation,aiming to establish an Evaluation Index System(EIS)from the angle of Tourism Safety Information and obtaining means.By doing so,the formula method is used to determine the weight,and the cloud focus theory is used to establish the evaluation model,which has a series of advantages,including the reduction of subjectivity,uncertainty and ambiguity in the evaluation process,the increase of objective and credibility.Make the evaluation result more objective and credible.The data from EIS shows that the evaluation result shows that the data form EIS have validity,which verifies the reliability of the evaluation model.The research result might offer a reference for tourism safety risk assessment in scenic spots.
