Along with the popularization and application of ground source heat pump technology, as a renewable resource, shallow geothermal energy had got much attention, and the energy resources evaluation affairs on the shallow geothermal had been underway. In lights of the geological characteristics in areas of shallow geothermal energy, the authors studied the safe yield, with emphasis on the introduction of the conventional evaluation methods of shallow geothermal energy exploitation quantity, and analyzed the applicability of the evaluation method under different geological features in northern Jiangsu plain terrains, according to the geological characteristics in the study area and the appropriate evaluation method for groundwater source heat pump exploitation quantity. The authors found that the underground water conversion method and the appropriate evaluation method for the buried tube ground-source heat pump exploitation quantity was just the field test method. It was confirmed that the two methods above could achieve high precision in shallow geothermal energy exploitation quantity evaluation in northern Jiangsu plain terrains.
