Abstract: Based on the monthly mean air temperature, 0~20cm shallow ground temperature data at the weather station in Tingri from 1980 to 2019, with climatic statistical methods, the changing characteristics of shallow ground temperature in Tingri County were analyzed. The results showed that the annual average ground temperature of all layers (except 5cm) in Tingri in the past 40 years showed a warming trend, and the warming range was 0.03~0.187℃/10a, the warming rate of 0cm was the largest, the warming rate of 15cm was the smallest, the ground temperature of 5cm showed an insignificant decreasing trend, the warming of all layers was the most significant in spring and winter, and the ground temperature of each layer except the 0 cm layer showed a cooling trend in summer and autumn. The annual mean ground temperature of each layer (except 5cm) had a sudden change since 2000s, and the sudden change point was not consistent in each layer, but the sudden change point was from relatively cold period to relatively warm period, on the layers of 0cm and 20cm had an obvious change from cold to warm before and after 2000s. The annual mean temperature warming rate of Tingri was larger than that of all layers and passed the 0.01 significance test. The trend and period of changing were similar to those of each layer, and the correlation between the annual mean temperature and temperature in the 20cm layer was the most significant. Ground temperature in the 5cm layer was significantly different from other layers.
