在长白山北坡5个垂直植被带的林下采集29个表土(苔藓)样品进行孢粉分析,同时将其结果作对应分析。结果表明,除个别样品,在长白山垂直植被带的孢粉组合中乔木花粉占优势,其中以松属和桦木属最多,在各植被带均有分布。松属花粉最高含量出现在以红松为主的针阔混交林带的孢粉组合中;桦木属花粉则大量见于亚高山岳桦林带和以栎桦为主的阔叶落叶林带,但前者伴有耐寒、旱的小灌从杜鹃花属花粉,而在后者中则见有大量蕨类孢子。阔叶落叶林带的孢粉组合是以类型多、百分含量高的落叶乔木花粉和大量蕨类孢子为特征。亚高山针叶林带的孢粉组合中出现数量众多的云杉属花粉。在高山苔原带孢粉组合中虽然乔木花粉略占优势,但极少或不见蕨类孢子,与其他植被带比较,草本植物和小灌丛花粉明鲜较多,其中杜鹃属花粉含量在草本中占优势,其中出现苔原带的指示花粉——仙女本属。
29 surface soil (moss) samples collected from 5 vertical vegetation belts on the northern slope of Changbai Mountain were collected for spore-pollen analysis, and the results were analyzed accordingly. The results showed that in addition to individual samples, arbor pollen dominated the sporopollen assemblages in the vertical vegetation belt of Changbai Mountain, of which Pinus and Betula were the most abundant and distributed in all vegetation belts. The highest content of Pinus pollen appeared in the spore-pollen assemblage of coniferous and broad-leaved forest dominated by Korean pine. Betulin pollen was found mostly in subalpine mountain birch forest and broadleaf deciduous forest dominated by oak birch, Hardy, dry small irrigation from Rhododendron pollen, while in the latter see a large number of fern spores. The broad-leaved deciduous forest belt sporopollen assemblage is characterized by a large number of high percentages of deciduous tree pollen and a large number of fern spores. A large number of Picea pollen appear in the sporopollen assemblages in the sub-alpine coniferous forest. Although the arboreal pollen slightly dominated in the pollen assemblages in the mountain tundra, few or no fern spores were found. Compared with other vegetation belts, herbaceous plants and scrub pollens showed more freshness, of which the pollen content of Rhododendron was higher in the herb The dominant pollen in the tundra zone appears - the fairy genus.
