北极地区是全球发生气候事件的敏感区 ,选择北极巴罗地区利用连续的湖泊沉积进行高分辨率的孢粉分析 ,恢复当地古气候与古环境是理想的。在北极地区的这种研究工作在我国尚属首次 ,其目的是通过对巴罗地区 9支湖泊钻孔岩心的孢粉及微体古生物与地球化学、放射性测年等综合研究 ,重建研究区 2 0 0 0年以来气候与环境变化序列 ,为预测未来 50年地区系统的区域乃至全球尺度的变化速率、幅度与趋势提供重要科学依据。
The Arctic region is the sensitive area where climate events occur in the world. It is desirable to use the continuous lacustrine sedimentation in the North Pole to carry out high-resolution sporopollen analysis and restore the ancient paleoclimate and paleoenvironment. This research work in the Arctic region is the first time in our country. Its purpose is to rebuild the study area 2 through comprehensive research on the sporopollen, micropontolite, geochemical and radioactive dating of the drilling cores in 9 lakes in Barrow area The series of climate and environmental changes since 2010 provide an important scientific basis for predicting the rate of change, magnitude and trend of regional and even global scales of regional systems in the next 50 years.
