中国晚第四纪湖泊水量变化和气候模拟比较研究

Construction of Palaeolake Status Data Base is not only to do data collections and make data base procedure, but a great of research work is also to analyse the data evidence and reconstruct the water balance from individual basins. This program studied the reconstructions of long-term changes in lake status from from China. The results have been to be used to provide basis of precipitation and P-E fields for the East Asian Monsoon areas, to rebuilt patterns of atmospherical circulation during the last 30 ka BP, and validate palaeoclimate simulations from the climate models.

中国地貌和气候系统是验证古气候模拟的理想背景；地质证据重建的古气候有待于模型动力机制解释。根据湖泊沉积地貌古生物等表征的气候信息，建立晚第四纪湖泊演化数据库，并与国际古气候模拟6Ka和21Ka降水与P-E比较。分析降水空间分布，水汽输送及古大气环流格局。探讨在全球变化框架中季风环流特点和动力学机制，为创建古季风理论作出贡献。
