摘　　要：兴文石海是四川省最先入选的世界地质公园,独特的僰、苗文化与"兴文式"喀斯特的完美结合使其成为我国20处世界地质公园中的奇葩。为评价地质公园地质遗迹对外界干扰的抵抗力,将敏感度概念引入地质环境的评价中。在分析石海区域地质环境基础上,选取气候、区域地质条件、地质灾害、土壤背景质量、地质环境破坏速率等7个评价要素和相应的20个评价因子,建立评价指标体系和数学模型;采用权重加权平均法,对公园内地质环境敏感度进行定量评价,提出兴文石海世界地质公园可持续发展的措施。The Xingwen karst geopark is the only world geopark in Sichuan Province at present. It is characterized by unique customs of Bo nationality and Miao nationality and ＂Xingwen-type＂ karst landform which make it an exotic flower among the 19 world geoparks in China. This paper introduces the sensitivity into assessment of geological environment in order to evaluate the influence of outside factors on the geoheritage in the Xingwen karst geopark. Regional geological condition, climate, soil condition, degradation rate, human beings activities as well as geological hazards were considered to be the key factors. About 20 elements were selected to construct a geological sensitivity assessment system and mathematical model which are applied to assessment of the geological environment sensitivity in Xingwen karst geopark. Some countermeasures for its sustainable development are put forward.
