The Evalution Of The Geological Sites And The Protection Reasearch In Changshan National Geopark

Geological sites have potential values in scientific research, science education, aesthetic, historical and cultural, tourism development, etc. Geological landscape, the typical geological profiles, typical geological paleontology, typical rock minerals, landscape, water landscape and environmental geological landscapes may be unique tourism resources due to its scientific, beautiful and important social value.There are too many geological heritage resources in Changshan National Geopark.Geological sites are basic elements of the geopark, and the comprehensive condition of its scientific value, aesthetic value, social value, development value determines the grade of geological park.Based on the analysis of previous studies, we completed on the evaluation index to construct the evaluation index system of geological sites of Changshan National Geopark; Through field investigation and literature, we made the qualitative evaluation with basis of the features of geological sites;Using AHP to determine the index weight, we constructed the quantitative evaluation model of geological sites of Changshan National Geopark. Geological sites of Changshan National Geopark were divided into national and above provincial and county 3 levels.The results showed that Geological Sites of Changshan National Geopark which reached the national level and above is 5, which reached provincial level is 11,and which reached the county level is 14. Using fuzzy comprehensive evaluation method,we analyzed and evaluated the geological environment sensitivity of Changshan National GeoPark, providing a basis for determining the protection level of geopark geological sites. The results showed that the geological environment of Changshan National Geopark is more sensitive.and it needed to implement and develop the protection scheme.Finally, according to results of the evaluation of geological sites and the geological environment sensitivity, it presented protection and utilization plan for Changshan National Geopark.,it had important theoretical value and practical significance to construction of geopark.
