How to assess the value of geological heritage?

The inventory and quantitative assessment of geological heritages have become a major issue in the establishment of geopark. The purpose of this study is to adjust the preliminarily adopted assessment model for comprehensive and objective assessment and to suggest improved grade standard. The model is divided into two parts, each with several sub-criterion. Main part of the evaluation aims at the value of the geological heritage, and sub-criteria are scientific/educational value, geomorphological/landscape value, historical/cultural value, instrinsic value, functional value, and economical value. The aim of the other part is to evaluate the aspect of conservation and management. We make up for specific and objective parameter for scoring system of each criterion and provide reliable grade standard diagrams using scientific/educational value and geomorphological/landscape value.
