- Abstract:
-
Different regions controlled by different dominant climatic factors show different characteristics of Holocene climate change. By the study of these mechanisms, we can have a very clear understanding on the developing process and the mutual coupling relation between the natural elements, as well as the impact of mechanism on climate. Through comparative analysis of Holocene climate changes in different regions of China, it is found out that the characteristics of Holocene climate changes in Northwest China and the Loess Plateau generally show that there are a dry and cold climate in the early Holocene, a warm and humid climate in mid-Holocene, a climate deterioration in the late Holocene, and two monsoon strengthening appearing in the southwest monsoon region and the eastern monsoon region during the Holocene. But the strengthening of the southwest monsoon is about 3~4 ka earlier than that of southeast monsoon. This paper argues that the characteristics of Holocene climate changes on the Loess Plateau and Northwest China are alike which may be due to the same climate system that affects them. While, the contrast of Holocene climate changes in Southwest Monsoon region and Eastern Monsoon region is pretty good which may indicate that both the strengthening and weakening of Southwest Monsoon and Southeast Monsoon are controlled the same by the north-south movement of planetary wind belt during Holocene. But the strengthening of the southeast monsoon delayed because of the huge heat capacity of ocean, resulting in the asynchrony of Holocene climate changes in Southeast Monsoon region and Southwest Monsoon region.
