基于AHP法地质遗迹资源定量评价及其应用研究

Quantitative evaluation of geological relic resources based on AHP and its application

层次分析法(analytical hierarchy process,AHP)是地质遗迹资源评价中应用较为广泛的一种方法,该方法的核心问题在于对其评价指标体系的构建。在AHP法的基础上,文章从地质遗迹资源的自身属性和开发利用条件2个方面构建了更为全面、实用的地质遗迹评价指标体系,形成了一套系统的科学的地质遗迹定量评价模式。该模式表明,地质遗迹资源自身属性在地质遗迹评价中所占权重最大(0.750),主导着地质遗迹资源评价的结果,是地质遗迹资源开发利用的基础,同时,外部开发利用条件也是资源定量评价不可缺少的元素。以安徽马仁山地质公园内各类型地质遗迹为对象进行了该模型应用研究,结果表明,研究区地质遗迹资源评价情况与实际相符,基于AHP法建立的地质遗迹资源定量评价模式具有一定的实用价值。

Analytical hierarchy process（AHP） is a method which is widely used in the evaluation of geological relic resources, the core problem of the method is the evaluation index system of geological relic resources. In this paper, a more comprehensive and practical evaluation index system of geological relic resources is established, and a systematic and scientific quantitative evaluation model of geological relics based on AHP is formed, which comprises the characteristics and development conditions of geological relic resources. According to the model, it is shown that the index weight of geological relics characteristics is the biggest one（0. 750） in geological relics evaluation, which dominates the re- sult of geological relics evaluation and is the basis for the development of geological relic resources. Meanwhile, development conditions are also essential external factors in the quantitative evaluation of resources. Taking the geological relic resources in Anhui Marenshan Geopark as an example, it is shown that the geological relic resources evaluation result is accordant with the actual situation in the geopark. Therefore, the geological relic resources quantitative evaluation model based on AHP has certain practical value.
