地壳温度测量在地球物理学及地震预报研究中都具有重要意义。在钻孔中进行温度梯度测量并与岩石热导率的测定相结合,可取得大地热流数据,以此可全面表征地表热场并展示地球内部热状态。在地震预报研究中,地温观测既可作为一种地震前兆观测手段,也可作为一种辅助观测项目,以便从其它观测手段中排除环境温度变化造成的影响。 Crustal temperature measurement is of great significance in geophysics and earthquake prediction research. Temperature gradient measurements in boreholes, combined with rock thermal conductivity measurements, provide data on the geothermal heat flow in order to fully characterize the surface thermal field and show the thermal state of the Earth’s interior. In the study of earthquake prediction, the geothermal observation can be used as both an earthquake precursor observation method and an auxiliary observation item to exclude the influence of the ambient temperature change from other observation methods.
