分析了我国172个测站40多年的气温观测资料和历史代用资料。1980-1994年，最暖年首先出现在青藏高原东南部，然后逐渐向北和向东扩展到中国东部。近600 a来世纪尺度上的气候变化表现为3个相对温暖和寒冷的阶段。各暖期和冷期均先出现在青藏高原，后出现在祁连山，最后出现在我国东部。青藏高原的冷暖期比东部早10-60 a。事实表明，在短于10（3）a的时间尺度上，TP是中国气候波动的先导区。
Over 40 a observed temperature data in 172 stations in China and historical proxy data were analyzed. Evidence suggested that during 1980-1994, the warmest year appeared first in southeastern part of the Qinghai-Xizang (Tibet) Plateau (henceforth SETP) and then gradually spread northwards and eastwards to eastern China. The climatic change on century time scale in recent 600 a shows 3 relatively warm and clod stages in China. Each warm and cold stage appeared first in Tibet Plateau (henceforth TP) and then in the Qilian Mountains, then in the eastern parts of China. The warm and cold stages in TP were 10-60 a earlier than in the eastern China. The facts show that TP is a pilot region of climatic fluctuation in China on the time scale shorter than 10(3)a.
