英文摘要: Long-term (1981-2014) trends in soil temperatures at depths ranging from 0-320 cm were used to examine relationships between regional climate change and soil temperatures in the Three River Source Region (TRSR) of the Tibetan Plateau (TP). Air temperature, precipitation, maximum depth of frozen ground and maximum snow depth were also analysed for trends and for correlations with soil temperatures. A significant warming trend was evident in the TRSR during the 35 yr analysed. Significant soil warming was detected, at rates of 0.706°C decade -1 for surface soils (0 cm), 0.477°C decade -1 for shallow layer soils (5-20 cm) and 0.417°C decade -1 for deep layer soils (40-320 cm). There was a clear effect of air temperature on soil temperature, as seen from the concurrent significant increases in air and soil temperature trends and the strong cor-relation between them. The relationship between precipitation and soil temperatures was com-plicated. Higher levels of precipitation on the ground also resulted in higher soil temperatures during the summer in the frozen soil, while the process of freezing and thawing had an inhibitory effect on the soil temperature increase. The warming trends in soil temperature are expected to continue with the degradation of frozen soil in the TRSR. © The authors 2016. Citation statistics:
