Abstract:

On the basis of the physical and chemical analyses of glacial lacustine sediment and glacial geomorphology in Diancang Mountain, the series of climate change since HoloCene is expected to be rebuilt, including 6 stages with the alternation of cold-wet and warm-dry climate. The comparison with other areas affected by southwest monsoon shows that the time when southwest monsoon arrived at Diancang Mountain was later than that of the Arabian Sea and earlier than that of the Tibetan Plateau. This fact implies that Diancang Mountain is the joint linkage of the above place. Another phenomenon is that after southwest monsoon arrived at the Tibetan Plateau, the climate of Diancang Mountain change slightly drier. The record presents that this area was influenced by southeast monsoon between 6.0 ka BP and 5.3 ka BP.

Key words: Diancang Mountain, lacustrine sediment, HoloCene, climate change
