利用1983年7月～1990年12月ISCCP卫星反演的地表温度资料，将高原的温度变化分为三个区。在每一区找1～2个温度变化的代用资料(冰芯、树轮)，将近600a的资料进行标准化处理，然后按面积加权，得到了大体可代表整个高原的平均温度变化序列，发现600a来高原上曾出现过三次冷期和暖期，最冷在17世纪中叶。

Three subregions are compartmentalized for temperature overQinghai-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.
