摘　　要：长白山岳桦林带表土花粉分析表明,除桦外,孢粉组合中的乔木植物花粉系其它林带传播而来,草本和蕨类植物孢粉组合代表了林下植被的特征,林带中主要建群种植物花粉与其植被的R值均小于1。并讨论了其它植被带孢粉组合与植被的关系。The surface pollen analysis in Betula ermanii forest of Changbai Mountain suggests that all trees pollen except Betula in pollen assemblage are transformed from other forest belts. The herbs pollen and ferns spores can present the main characteristics of sublayer vegetation of the forest. But the pollen percentage of the main dominant species in pollen assemblage show low contrast with their vegetation. The relation ship between pollen assemblages and vegetation in other forest belts are also discussed.
