摘要/Abstract

摘要： 白洋淀湖面捕捉器样品、湖底捕捉器样品和湖泊表层沉积物样品花粉组合及花粉通量均能较好地反映地方和区域植被特征。湖面捕捉器花粉通量明显低于湖底捕捉器,通过对比湖面、湖底捕捉器花粉通量,发现白洋淀湖泊有91%以上的花粉由地表径流携带而来。判别分析结果表明:湖水和空气在花粉传播和沉积过程中均存在对花粉的搅匀和混合作用,样品类型间花粉组合差异大于样点间差异,花粉来源途径的不同对湖泊花粉组合影响明显。

Abstract: Pollen assemblages and pollen influx of trap samples upon water and under water and surface sediment samples from Baiyang Lake reflect regional and local vegetation well. Pollen influx of trap samples upon water are lower than those under water obviously, indicating that there is about 91% of total pollen being transported through water in the lake. Discriminant analysis shows that there was preferable mixing effect when pollen was transported and sedimented through air and water, and the difference of pollen assemblage among different sample types is more obvious than among different sample sites.
