Abstract：Using the daily temperature data(daily average,maximum and minimum temperature)from 76 stations on the Qinghai-Xizang Plateau over the past 43 years,the temporal and spatial distribution characteristics of changes in temperature as well as onset and ending time of the four seasons on the Qinghai-Xizang Plateau over recent de-cades were analyzed in detail.The results showed that most areas of the Qinghai-Xizang Plateau had experienced an upward trend in the average,maximum and minimum temperature from 1974 to 2016,with the minimum tempera-ture rising faster than the maximum temperature,leading to a downward trend in the daily temperature range.Be-sides,according to the main characteristics of seasonal changes on the Qinghai-Xizang Plateau over recent decades,winter and autumn experienced delayed onset and shortened duration while spring experienced significantly ad-vanced onset and sightly increased duration,and summer experienced advanced onset and significantly increased duration.In consequence,the impacts of climate change are profoundly changing the temperature and the seasonal transitions of the plateau near-face.
