摘要
为评价光雾山国家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遗迹的评价中。在分析该区地质环境的基础上,总结了主要影响因素;选取气候、区域地质条件、地质灾害、土地背景质量、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,建立了评价指标体系和数学模型;采用权重加权平均法,对区内地质环境质量进行分区评价,为研究区地质环境保护和利用提供了依据。
In order to evaluate the influence of outside factors on the geo-remains at Guangwushan Mountain National Geo-park in Sichuan Province, the sensitivity degree was defined to assess the a situation of geo- remains. After analyzing the geo-environment in the geo^park, the main factors was concluded. Regional geological condition, water resources, soil condition, degradation rate, human beings activities as well as geohazards were considered to be the seven key factors. About 20 elements were selected to construct a geological sensitivity assessment system and the Weight Average Methodology as a mathematical model is applied to deal with the geological environment sensitivity assessment in Guangwushan Mountain National Geo-Park. Accordingly, the assessment system will help the protection and exploration for geological resources geo-park.
