摘　　要：旅游生态灾害已经成为影响全球旅游业可持续发展的重要问题。为了描述生态灾害对旅游目的地系统的影响程度,根据自然灾害的成灾原理,利用灾害危险性、系统的脆弱性和防灾救灾能力来综合评价旅游目的地系统的生态灾害风险,并根据评价对象的特殊性选取相应评价指标-用灾害发生的频度和破坏性来评价灾害的危险性;从旅游者、旅游资源、旅游生态环境和旅游经济四个方面来评价系统的脆弱性;根据预警和救灾恢复两方面评价防灾救灾能力。利用模糊物元模型、加权综合评价法和层次分析法,计算得出旅游目的地系统的生态灾害风险指数。这一结果能定量地衡量生态灾害对旅游业的威胁,为旅游地及时认清形势,采取及时有效的措施规避风险,提高自身防灾抗灾能力提供依据。Ecological disaster has already become a serious obstacle to the sustainable development of tourism industry.In order to describe the influence of ecology disaster to the tourism system we established a ecological disaster risk assessment model consisting of risk index,vulnerability index and cure risk ability index according to the theory of natural disaster engender process.In view of the three indexes,we selected the corresponding evaluating indicator and used the fuzzy element model,the weighting quality synthetic evaluation law and the analytic hierarchy process to get the ecology disaster risk index of tourism system of destination.The assessment result can quantificationally weights the threat to the tourism from ecology disaster and provides the basis of adopting the prompt effective measure to avoid the risk for the traveling,while enhances the self-protect ability of tourism destination system to resist ecological disaster.
