【摘要】 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。更多还原

【Abstract】 As the Arctic is sensitive to the global climatic events, Barrow is an ideal region whose lake’s deposit is selected for high resolution pollen analyses to reconstruct palaeclimatic and palaeenvironment. This is the first time for pollen study in China. The aim is to reconstruct the sequence of climatic and environment in the past 2000 years by the comprehensive study of pollen, micropalaeontology, geochemistry and radiocarbon dating on 9 lake cores from Barrow. The result can provide important science data for anticipating the change rate, range and tendency of climatic and environment of area of the Earth system or even of the globe.更多还原
