Abstract: Geothermal energy, as a green, low-carbon, clean and environmentally friendly renewable energy source, will play an important role in the national energy reform process.Studying the evaluation of geothermal resource development constituencies is of guiding significance for relevant government units and enterprises to formulate development plans.According to the typical characteristics of geothermal resources, this paper establishes a more comprehensive evaluation index system for geothermal resource development constituency from the seven evaluation levels of resource advantages, geological conditions, environmental impact, technical level, policy risk, economic benefit and management system.The hydrogeology expert group, the geothermal resource development technical expert group and the geothermal resource economic evaluation expert group are established to judge the geothermal development plan, and the geothermal development plan is ranked by the gray correlation degree and the ranking method that approximated the ideal solution.The results show that the evaluation system can objectively reflect the own attributes of each program; this method can not only evaluate the overall status of each program, but also reflect the difference between the internal trend of the affected factors and the ideal solution.It has certain reference value for the evaluation of geothermal resource development constituency.
