中文摘要:地质遗迹景观脆弱性是地质遗迹景观系统对人类活动和自然条件变化反映的重要指标,是评价地质遗迹景观可持续利用的重要指标。文章以永福县典型地质遗迹景观为例,运用地质遗迹景观脆弱性影响因素压力-状态-响应(PSR)模型,从压力、状态、响应3个层面选取17个评价指标,构建地质遗迹景观脆弱性评价指标体系,采用层次分析法(AHP)确定各项指标权重,并运用德尔菲专家咨询法建立5级地质遗迹景观脆弱性划分标准,最后通过综合评分法对永福县地质遗迹景观脆弱性进行评价。结果表明:永福县地质遗迹景观顶子山、小山峡评价值为16.797 0、19.142 1,属微度脆弱;福禄泉、石占溪瀑布评价值为 39.162 8、39.777 5,属低度脆弱;拉孝江、百寿河、板峡湖评价值为 58.546 5、52.330 5、 52.520 9,属中度脆弱;百寿岩、新村屯洞、永福岩评价值为 65.743 0、64.089 3、72.939 5,属高度脆弱,这与实地调查结果相吻合,反映出永福县地质遗迹现状,由此说明PSR模型评价地质遗迹景观脆弱性具有实用性。

Evaluation of the vulnerability of geological heritage landscape based on PSR model: Taking Yongfu county as an example
Abstract:The vulnerability is an important index of geological heritage landscape system to reflect human activities and natural conditions. It is also an important index to evaluate the sustainable utilization of geological heritage landscape. Taking the typical geological relic landscape in Yongfu county as an example, and adopting the PSR model of influencing factors of vulnerability,the paper selects 17 valuation indicators from three levels of pressure, state and response to construct the indicator system of vulnerability evaluation for the geological heritage landscape in Yongfu county. The analytic hierarchy process (AHP) is adopted to determine the evaluation factor weight of vulnerability, and 5 classification criteria for vulnerability grade of geological heritage landscape are established by the Delphi Method. Finally, the comprehensive scoring method is used to evaluate the geological heritage landscape in Yongfu. The results show that vulnerability grade of Dingzi hill and Xiaoshanxia in Yongfu is respectively 16.7970 and 19.1421, being slightly vulnerable; the grade of Fulu spring and Shizhanxi waterfall is respectively 39.1628 and 39.7775, mildly vulnerable; the grade of Laxiao river, Baishou river and Banxia lake is respectively 58.5465, 52.3305 and 52.5209, moderately vulnerable;the grade of Baishou cave, Xincuntun cave and Yongfu cave is respectively 65.7430, 64.0893 and 72.9395, highly vulnerable. These values are consistent with the results of field survey, and can basically reflect the current situation of geological heritage in Yongfu county. illustrating the applicability of PSR model to the vulnerability evaluation of geological heritage landscape.
