An Evolution of Holocene Environment in the North of Taklimakan Deesert

Feng Qi; Wang Jianming

The main sediments of Holocene sections are clay and sand soil with mini-sand layers in North Taklimakan desert. The evolution of Holocence environment in the North of Taklimakan desert is revealed by analyzing the characteristics of granular, change of chemical composition, sporopollen composition, content of CaCO₃ and mineral. The Holocene climate is a rid and changes between hot-dry and cool-dry, which is mainly controlled by global longitude wind and cyclone. The region climate change, comparing with global climate change, and the climate gradually become arid and the environment become more deterorated with the global clima te become drier in recent years.

Abstract: The main sediments of Holocene sections are clay and sand soil with mini-sand layers in North Taklimakan desert. The evolution of Holocence environment in the North of Taklimakan desert is revealed by analyzing the characteristics of granular, change of chemical composition, sporopollen composition, content of CaCO₃ and mineral. The Holocene climate is a rid and changes between hot-dry and cool-dry, which is mainly controlled by global longitude wind and cyclone. The region climate change, comparing with global climate change, and the climate gradually become arid and the environment become more deterorated with the global clima te become drier in recent years.
