The Methods of Investigation and Evaluation of Geological Heritage Resources

In recent years,the application and construction of Geopark have developed rapidly,but the research of theory and method of geological heritage investigation and evaluation is little.In this paper,the methods of geological heritage investigation and evaluation are studied systematically on the basis of Geopark application and construction projects.We designed the technological process of geological heritage investigation and evaluation,the process includes 4 steps such as data collection,field investigation,scientific research,resources evaluation,writing reports etc.The contents of geological heritage investigation are summarized;the investigation method is from point to line,then from line to area.The quality control methods of investigation are put forward.The contents of evaluation are geological heritage element,value and condition of exploitation and using.The method of evaluation is qualitative and quantitative.The index system of quantitative evaluation is established and the factor weight is distributed using AHP(Analytic Hierarchy Process).At last,the grade of geological heritage can be determined using fuzzy mathematical model.The projects accomplished show that these methods of investigation and evaluation have better applicability and universal significance.
