黄海大气中的孢粉及其对海底沉积物中孢粉组合的影响

STUDIES ON ATMOSPHERE SPORES AND POLLEN AND THEIR INFLUENCES ON THE SPOROPOLLEN ASSEMBLAGES IN THE SEDIMENTS OF HUANGHAI SEA

１９７８—１９７９ 年在黄海上空共收集到孢粉３２１ 粒，属２３ 个属种。春季大气中所含孢粉数量最多，秋季次之，夏季和冬季较少。大气中木本花粉含量达７４％ ，草本花粉２３％ ，孢子３％ 。通过大气中孢粉与１９９０ 年黄海表层沉积物中孢粉组合的对比，反映出大气中孢粉与海洋沉积物中孢粉属种具有明显的对应关系。海洋沉积物中的孢粉分布显现近岸草本花粉含量高。

Totally, 321 grains of spores and pollens which consist of 23 genera and species, were collected from the atmosphere over Huanghai Sea during the survey in 1978—1979.It has been found that the amount of spores and pollen in the atmosphere was high in spring, lower in autumn and the lowest in summer and winter.The content of arboreal pollens amount to 74%, with 23% of herbaceous pollens and 3% of spores.By comparing the spores and pollens in the atmosphere with those in the marine sedments it was revealed that the they were well correlated but the former influences distinctly to the distribution of the latter, thus making a high content of herbaceous pollens in the sporopollen distributions in the marine sediments nearshore area and high content of arboreal pollens in area far from the coast.
