Effects of GSHP system on thermal environment of vegetation growth in Olympic Forest Park

In order to analyse the influence of ground-source heat pump (GSHP) system on vegetation, monitors the underground temperature（0.5 to 3.1 m） during the operation of the system. Analyses the influence of GSHP on the underground temperatures. The results show that the influence of the GSHP on the underground temperature decreases with the increase of the depth and the distance from GSHP, and the influence of GSHP on the annual variation and the variation range of the underground temperature is less. Meanwhile, after weighted average of the ground temperature of the shallow layer according to their respective depths, the data show that the influence of the GSHP on the temperature field is limited. Therefore, the influence of the GSHP on the vegetation in the Olympic Forest Park is also limited.
