近年来,地理科学学院微体古生物团队(主要成员陈春珠,李焕和赵文伟博士)基于孢粉记录开展了植被和气候重建的系列工作,通过大量植被重建结果与气候模式结合进行了全球、东亚和亚热带区域的气候变化和机制研究。近日,在国际期刊《Climate of the Past》、《Journal of Geophysical Research: Atmospheres》、《Journal of Quaternary Science》和《Palaeogeography, Palaeoclimatology, Palaeoecology》和国内期刊《微体古生物》上分别发表学术论文(题目见下)。

 

目前团队的主要研究内容:

1、长期围绕长尺度的记录开展高纬和高海拔地区(北极圈和青藏高原东北部等区域)的孢粉记录重建植被演化历史,尝试探讨轨道-亚轨道参数下植被与气候的演化历史和机制;(成果见5

2、开展亚热亚高山泥炭湿地古气候记录研究,来弥补该区域的研究空白,该区域由于人类活动强烈和沉积不连续等问题的困扰;(成果见36

3、结合植被演化历史记录与地球系统模式,通过记录数据同化和模式模拟研究特征阶段的气候与植被响应机制。(成果见124
