Abstract:
Analytic hierarchy process (AHP)-fuzzy comprehensive evaluation model can be applied to effectively solve the problems caused by traditional evaluation methods, which are the difficulty in quantitative assessment and the subjective effects on fuzzy concept's, so that the evaluation results are more reasonable and accurate. The researchers in this paper have adopted 7 factors, including single rock mass, depth of groundwater, total thickness of aquifer, lithology of stratum, thermal conductivity, heat capacity and soil temperature, to evaluate the adaptability of shallow geothermal energy of Changle County in Shandong Province by AHP-fuzzy comprehensive evaluation model. The research area was divided into two subsections, including medium suitability areas of 44.71 km
2 and poor suitability areas of 10.29 km
2. The study areas were further divided into general development zone, encouraging development zone, vigorous development zone and restricted development zone, combined with the urban planning of Changle County. The shallow geothermal energy in the study area has the greater potential, and the reasonable development can bring huge economic and social benefits.
