In this study, a monthly dataset of temperature time series (1961-2010) from 12 meteorological stations across the Three-River Headwater Region of Qinghai Province (THRHR) was used to analyze the climate change. The temperature variation and abrupt change analysis were examined by using moving average, linear regression, Spline interpolation, Mann-Kendall test and so on. The main results contained 3 aspects, which were the long-term trends of temperature at different scales (inter-annual, interdecadal and 30-year scales), the spatial variations of annual and seasonal average temperature from 1961 to 2010, and the abrupt change of temperature in the THRHR and its 3 sub-headwater regions. These results could provide the basic data and reference for the ecological construction and protection in THRHR
