摘要
Based on monthly mean temperature and precipitation, the changing processes and tendencies of temperature and precipitation in Qinghai-Xizang Plateau from 1950s to the early 1990s are analysed. The change of temperature in the past 40 a is almost unanimous on the spatial scale. The first area becoming warmer is the southeastern Tibet. The plateau is divided into 5 parts according to the change of temperature, and 9 parts according to the change of precipitation. For the past 40a some area has been warmer and drier, others warmer and wetter.
