基于博弈组合赋权-云模型的区域地热开发适宜性评价OA

With the acceleration of urbanization in northwest Shandong,the demand for heating in winter has increased sig-nificantly,and the supply of traditional energy tends to be tight.To ensure energy security and sustainable development,it is crucial to scientifically evaluate the advantages of geothermal resources.In this paper,the northwest Shandong Province is taken as the research object,and the comprehensive weight of each evaluation index is determined by combining the charac-teristics of the geothermal field,geothermal reservoir characteristics,and regional development needs,using the game combi-nation weighting method of variation coefficient method,CRITIC method,gray correlation method,and projection pursuit method.By using the cloud model to sddress the fuzziness and randomness in the evaluation,the suitability grade is deter-mined by comparing and analyzing the actual cloud picture with the standard cloud picture of the evaluation unit,thereby en-abling regional geothermal suitability evaluation.The results show that the areas with"good"suitability in the study area are distributed in Dezhou latent fault depression,Gaotang latent fault uplift,and Gucheng-Guantao latent fault uplift.Gross na-tional product,thermal storage temperature,and thermal storage thickness are the key factors affecting the suitability of geo-thermal development in the study area.The research results can provide a reference for optimizing the regional geothermal re-sources exploration target area.
