Using the air temperature data based on the China Meteorological Stations and the surface temperature data from National Centers for Environmental Prediction of America,the temperature changing extraction of 15 cases of M_S≥5.0 earthquakes from January,2010 to December,2014 in Tibet was studied. The results showed that air temperature enhancement anomaly appeared in 12 cases before the earthquake,and surface temperature enhancement anomaly appeared in 13 cases. There were 10 earthquakes which had the two kinds of temperature increment phenomena. Moreover,the peak date of two data were very close. It is mutually confirmed that there was rising land round temperature before moderate-strong earthquakes in Tibet.
