摘要
通过对鄱阳湖ZK01钻孔的近7300-50BBP孢粉记录进行研究。根据岩芯中孢粉主要种属类型及含量变化特征共划分出9个孢粉组合带。同时根据孢粉记录尝试恢复了鄱阳湖流域的古植被和鄱阳湖区的水域面积变迁特征，以及地区气候冷暖变化。其中利用亚热带乔木花粉和山地针叶林植物花粉之间百分比含量差值的变化特征，对鄱阳湖流域近2760aBP以来的冷暖气候变化进行较为详细的探讨。
Through the study the spompollen record of drilling hole ZK01 in Poyang Lake during 7300 to 50a BP, nine sporopollen zones are divided according to main types of genera and species and diverse characteristic of sporopollen contents in rock core. The paleovegetation in Poyang Lake river basins and the transitional feature of water area as well as cold and warm variation of paleoclimate in Poyang Lake region are recovered by sporopollen record. According to variation characteristics of the percentage content metabolic earmark of subtropical arboreal dust with conifer floral dust in hilly country, the cold and warm variations of climate of Poyang Lake river basins have been discussed in detail since -2760a BP.
