南充凌云山省级地质公园地质环境敏感度研究

Geoenvironment sensitivity assessment on Lingyunshan provincial geo-park in Nanchong

四川南充凌云山以其独特的丹霞地貌,加之神秘的佛、道教文化,享有"果郡灵山"之美誉。为评价凌云山省级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。在分析凌云山区域地质环境的基础上,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,对凌云山地质公园内地质环境质量进行评价,并提出凌云山省级地质公园可持续发展的建议。

Lingyunshan in Nanchong is characteristic of unique red loam landforms, and enjoys a reputation of Buddhist and Taoist cultures. In order to evaluate the influence of outside factors on the geological relics at Lingyunshan provincial geo-park in Sichuan Province, the authors summarized the main affecting factors based on the analysis of regional geological environment in the geo-park, the main evaluation factors were concluded, they were climate and regional geological conditions, geological disasters, soil background conditions, geological environment degradation rate, human activities and so on. About 20 elements were selected to construct a geological sensitivity assessment system and the weighted average method as a mathematical model was used to deal with the geological environment sensitivity assessment in Lingyunshan provincial geo-park.
