Tourism can have both positive and negative outcomes for residents in tourism destinations, It is a good method to analyze the status of tourism impact by means of investigating residents' perceptions of it. Various methods have been used in previous authoritative studies. However, owing to inherent imprecision, difficulties always exist in some conventional methodologies when describing the interpretation of linguistic or measured uncertainties for real-world randoln phenomena. The purpose of this research is to present the fuzzy synthetic evaluation method to investigate residents' perceptions of tourisln impacts. At first, basic attributes and a hierarchical framework of tourism impacts are defined and formed. Secondly, the weighted vectors are determined according to the knowledge and experience of experts. Thirdly, the weighted evaluation matrices are aggregated to get the fuzzy sets of tourism impacts. In the last stage, the final fuzzy sets are defuzzified to get the rank of the residents' perceptions of tourism impacts. A case study in Jiuzhaigou National Park of China is provided to demonstrate the application of this method. 相似文献

1INTRODUCTIONCommunity residents form an important part of tourismdestinations and play a crucial role in the protection anddevelopment oftourism resources. The Tourism Agenda21 advocates that the development of tourism industryshouldconsider the interestsofthe host residentsand en-sure long-term viability beneficial towards destinationcommunity (LIU, 2000).
