Abstract: By analyzing the meteorological data at weather stations of Gonghe, Guinan, Heka and Shazhuyu of Qinghai province during last three decades, it is referred that the modern climate of this region is characterized by lower air temperature and high fluctuation of cold and worm weather, by inadequate precipitation and frequent variation, by strong wind force and high frequence and by long frost season without absolute free-frost days.From the viewpoint of climatic classification, this region belongs to climatic zone of semi-arid steppe and arid desert in the temperate zone of Qinghai-tibet plateau.According to the facts of 30 years variations of temperature and precipitation and of minimum frequences of occurrence of high temperature and adequate precipitation, it is presented in the study that, to the end of the Century and the early of next Century, the temperature-increasing effect will be caused along with the human activities and the climate in the region will be possible to be more drier if even no greater fluctuation of natural dynamic changes of temperature and precipitation took place.
