| 摘 要： | Temperature variations on the Tibetan Plateau during the last millennium are revealed by comparing a Qamdo tree-ring δ13C, the Dasuopu ice-core δ18O series, and a previous composite temperature reconstruction. Results show that an obvious warm period during 1200-1400 AD corresponds to the Medieval Warm Period (MWP) when summer temperature was 1.2℃ higher than the recent 1000 years average, and a cool phase from 1400 to 1700 AD, with summer temperature being 0.5℃lower than long-term average, can be correlated to the Little Ice Age (LIA). The 13th century was the warmest phase during the past 1000 years, while the coldest period occurred during 1000-1200 AD. The 20th century warming was characterized by rapid winter temperature rise while summer temperature at that time displayed a slight downward trend.
