Abstract
Three subregions are compartmentalized for temperature over Qinghai Xizang Plateau based on the ISCCP surface temperature data during July 1983～December 1990. Ice core and/or tree ring data in the past 600 years are chosen in each subregion and then the data are computed into the air temperature index with the method of standardization and area proportioned. Variations of air temperature index show that three times of cold and warm periods appeared in the past 600 years. It is the coldest in the middle of 17th century.
