基于层次分析法—变权函数的青岛市灵山岛地质遗迹定量评价研究

Quantitative Evaluation of Lingshan Island Geological Relics in Qingdao City Based on Analytic Hierarchy Process Variable Weight Function

摘要:

地质遗迹评价和区划是地质遗迹资源科学保护与合理开发的基础，对地质遗迹保护区划及科学开发意义重大。本文通过层次分析法分级定等，针对该评价方法权重值各指标值大小在不同评价单元内始终不便的弊端，创新性地引入了变权思路，建立了变权理论的地质遗迹评价系统。以青岛市灵山岛为研究对象，对已经发现的30处地质遗迹进行了等级评价，权评价结果和变权修正，发现变权评价模型能在一定程度上克服指标内部差异性带来的不良影响，评价值离散性更好，有利于等级划分，评价结果更符合灵山岛实际特点。

Abstract:

The evaluation and zoning of geological relics are the foundation for scientific protection and rational development of geological relic resources. It has great significance for the protection, zoning, and scientific development of geological relics. By useing the Analytic Hierarchy Process (AHP), geological relics are classified and graded.The idea of variable weight has been innovatively introduced to address the disadvantage of inconvenient weight values of each indicator in different evaluation units. A geological relic evaluation system has been established based on variable weight theory. Taking Lingshan Island in Qingdao city as the research object, 30 geological relics that have been discovered have been evaluated. Through comparative qualitative evaluation, fixed weight evaluation results and variable weight correction results, it is showed that variable weight evaluation model can overcome the adverse effects caused by internal differences in indicators in some extent with better dispersion of evaluation values. It is conducive to grade classification, and the evaluation results are more in line with actual characteristics of Lingshan Island.
