A Study on the Division of Appropriate Rank of Shallow Geothermal Energy Resources Based on AHP in the Beijing Plain
In this paper,the division of appropriate rank of shallow geothermal heat pumps is constructed by considering the main impact factors of efficacy of water and ground source heat pumps.First,the impact factors of the two kinds of heat pumps are determined and the evaluation systems are set up.Then the weights of the factors are determined based on AHP and the appropriate coefficients of heat pumps are calculated on each 1 km × 1 km grid based on the comprehensive coefficient method.Finally,the division of the appropriate rank is made based on the appropriate coefficients.The area of appropriate and less appropriate zones to water and ground source heat pumps is 1381 and 3504 km2,the area of general zone is 1760 and 1075 km2,the area of forbidden and inappropriate zones is 2997 and 1559 km2.This result offers a scientific basis for the development and utilization of shallow geothermal energy resources and heat pumps in the Beijing plain.
