Based on study of the method of suitability zoning of shallow geothermal development and utilization in Anhui Province, this paper put forward a method combining key factor method, analytical hierarchy process and synthetic index, with shallow geothermal energy occurrence, technical, economic and environmental conditions as assessment factor, and key factor as necessary condition. This comprehensive assessment method can objectively reflect suitability features of development and utilization the assessment area. Suitability zoning is an important fundamental work that runs through the whole process of shallow geothermal energy investigation and assessment and guides reasonable development and utilization. The choice of zoning method and assessment factor should suit the local conditions.
