| The geological heritage is refers to during the long geologic history time which the Earth evolves, forms, develops and preserves preciously, the non-renewable geological natural heritage as a result of the inside and outside power's geological process, does not have renewability, non-region integrity, non-recoverability, not characteristics and so on probability, complex multiplicity and multi-disciplinary.. These geological products are the important basis for human understanding of the Earth's history, but also the important ways to access the valuable Earth's evolution information. Although these geological heritage do not necessarily have direct economic value, most of the they own potential value for scientific research, education, popular science education, disaster and environmental education, enlightenment education. Among of them, the geological landscapes, important ancient human sites and other natural disasters may become tourism resources due to their importance, unique, beauty and education value.Research on the use of geological heritage has begun to mature at home and abroad currently. Through the construction of geoparks on the promotion of geological heritage protection and development has reached a consensus point of view, therefore, the current geological heritage of more research on the use of geoparks in the building. China government attached much weight to the geological heritage protection, especially the establishment of national geoparks on behalf of the Government, in order to achieve effective protection of geological heritage and geo-ecological environment, promote the popularization of science Earth and Earth science research, expanding the employment of local residents and promote the sustainable development of the local economy.Geological heritage is the foundation for building geoparks, its natural attributes, the value of property, protection management, development conditions, and other elements directly determine the characteristics of geoparks in rank and scale.Therefore, in the construction and development of geoparks, geological survey and evaluation of the heritage is the importance part of the work. Existing geological heritage evaluation either too much emphasis on its scientific value and established a complete set of geological heritage applicable to the evaluation system of protected areas, or in geological heritage the same as the general tourism resources, too much emphasis on its aesthetic value to the neglect of its scientific value;"China's national geoparks construction work and guidance" also failed to quantify in the landscape of geological evaluation. So, geopark geological heritage characteristics of the basis of quantitative analysis of geological heritage build geoparks comprehensive evaluation model for China's geopark construction and development of great theoretical value and practical significance.Based on this, the paper of the existing system of indicators to complement and building a geopark geological heritage evaluation index system Analytic hierarchy process and Delphi method are used to determine the weight indicators. Combined level of law and grey system theory (that is, grey multi-level approach) construction of a geopark geological heritage evaluation In addition, to verify the scientific nature of the assessment model, reasonable, Guangxi five national geopark geological heritage a comprehensive evaluation.Papers were divided into five parts:Partâ… : Analysis of the background research, analyzed geopark geological heritage relevant theories, and geopark geological heritage evaluation index system of dynamic, this index system for the establishment of reference;Partâ…¡: In-depth analysis of geopark features on the basis of the existing system of indicators to improve added that the establishment of geological heritage Geopark Evaluation System;Partâ…¢: The more comprehensive evaluation of indicators and evaluation methods of research, selected Delphi method and level of analysis of indicators weight; accordance with the number of targets and indicators of the characteristics of selected grey-level analysis and theory building geopark geological heritage assessment model;Partâ…£: An Empirical Study. Guangxi to the existing five national geo,parks as an example, one of a comprehensive evaluation of geological heritage, to verify the text in the construction of the scientific assessment model and practicality;Part V: Conclusion. This paper on the work done by a summary of the conclusions drawn this paper, and the need to further study and improve the local and future research directions.The conclusions summarized as follows:â‘ on the existing geological heritage evaluation index system for the perfect complement, an increase of "development conditions" of indicators, building a geopark geological heritage evaluation index system; The system consists of three parts: target layer, four first grade indexes (natural attributes, the value of property, protection and management foundation, the development of conditions) and 15 secondary indicators.â‘¡application-level analysis and the Delphi method to calculate the various indicators of weight, and with grey multi-level analysis of the construction of geological heritage evaluation model. The evaluation model content includes: one evaluation matrix of first grade indexes and second index, and the assessment of the comprehensive evaluation of target. This universal model can be used to evaluate various types of geoparks in the geological heritage;â‘¢empirical research on five national geoparks in GuangXi, calculate the comprehensive evaluation value of various geopark geological heritage, and their development potential be a sort, while identify natural geological properties, the value of property, protection and management basis, conditions for the development to be respective grades, the results consistent with the actual situation, which proves the scientific and practical of our evaluation model.The innovations:â‘ through the analysis of geological characteristics of the park, found the heritage of the geological evaluation of a grey. This paper will first grey system theory into the geoparks in the assessment of geological heritage, the use of AHP and grey system theory with the construction of geoparks geological heritage comprehensive evaluation model.â‘¡Construction of the assessment model used in Guangxi five national geopark geological heritage to evaluate, on the evaluation of the current less. The evaluation that five national geopark geological heritage of the development potential of sorting, and various geopark geological heritage of the natural attributes, the value of property, protection and management foundation, the development of conditions for their grade. After the evaluation of the results can geoparks reference and provide development assistance.
