[Objective] We aimed to study the spatial and temporal variation of land surface temperature in order to provide a scientific basis for the further understanding of regional land-atmosphere interactions and surface energy exchange in China.[Methods] By statistical analysis, the spatial change of ground temperature in recent 50 years in China has been discussed.[Results] (1) In recent 50 years, the average ground temperature in China showed an increasing trend at a rate of 0.29℃/10 a. Significant increase occurred since 2000. The ground temperature in recent 50 years has increased in all seasons, while it increased most in winter.(2) The spatial distribution of ground temperature showed an increasing trend from the north to the south in all seasons, but it was slightly different in different seasons.(3) In recent 50 years, in most area of China, the ground temperature increased dramatically, especially in the north part of China, the increasing rate of temperature reached to 0.2~0.6℃/10 a.[Conclusion] In recent 50 years, the average surface temperature of China showed a significant increasing trend, and spatially increased from the north to the south.
