The invention relates to a test method of the underground temperature field of a ground source heat pump. The method comprises the following steps that (1) several groups of thermocouple wires are inserted into a plastic sheath pipe; (2) the plastic sheath pipe is linearly and fixedly arranged in a gap of pipe walls of adjacent ground buried pipes along the ground buried pipes by a plurality of plastic sealing strips; (3) the ground buried pipes are vertically buried under the ground, after the back filling, the several groups of thermocouple wires are connected with a multifunctional data collection instrument, and then, the data collection is carried out. The test method has the advantages that the method is simple, the implementation is easy, the defect that the thermocouple wires can easily facture through being pulled in the ground buried pipe installation and back filling processes is effectively overcome, the effect of measuring the distribution condition of the rock body temperature around the ground
