Abstract: In order to provide a significant scientific basis for geoheritages conservation and utilization in Hunan Province, on the basis of investigation, the authors summarize and research the evaluation principles, methods, process and results of the geoheritages in the province. The evaluation principles include overall system principle, classification evaluation principle and comprehensive evaluation principle. The evaluation process covers qualitative evaluation, quantitative evaluation, comprehensive evaluation and expert examination. In the qualitative evaluation, the expert qualification method is combined with comparison method. In the quantitative evaluation, the evaluation indexes and their categorical weighting are provided by Analytic Hierarchy Process (AHP). The comprehensive scores are calculated with fuzzy mathematical model. The comprehensive evaluation is the combination of qualitative evaluation and quantitative evaluation. The whole evaluation process is associated with experts' full participation and the cooperation between investigation team and the expert team. The evaluation results show that there are 518 important geoheritages in Hunan Province, of which 10 are world-class, 169 are national level and 339 are provincial level. With the geoheritages evaluation result, a good effect of geoheritages conservation and utilization has been achieved.
