摘　　要：基于热电比拟分析的理论,建立了地源热泵土壤热物性热电比拟的测试模型,并搭建了地源热泵土壤热物性测试实验台;对实验数据进行分析后,得出了西安地区土壤热物性参数的数据,验证了热电比拟模型测试土壤热物性参数的准确性。文中提出的热电比拟模型为土壤热物性测试提供了一个新的途径,对地源热泵的推广有积极的意义。A new test model of soil thermal properties was presented b ased on the assimilate heat and electricity theory and the corresponding test platform was established. Then the experimental test was carried out and the test date was analysed. It obtained the soil thermal properties of Xi＇an area and proved the accuracy of this mode. The new test mode offered a new way of testing the soil thermal properties. It has positive significance for the extension of ground source heat pump.
