Abstract: Geothermal exploration involves a high degree of uncertainty and financial risk. Establishing spatial relation between the known hot springs and evidence factor maps based on GIS technology. Then the assessment of geothermal resources in the study area was made. Earthquake epicenter, faults, Bouger gravity anomaly, magnetic anomaly, intrusive rock and heat flux datasets are selected as evidence factors. The fuzzy logic model was built and illustrated in western Anatolia, Turkey. Fuzzy logic model was applied to the evaluation of geothermal potential in Fujian Province. The geothermal potential of Fujian Province was divided into four levels; extremely high, high, medium and low potential area. The area with extremely high and high potential accounts for about 28.24% of the study area, including 59.11% of the total known hot springs. The research results have theoretical and practical significance for the development of concealed geothermal.
