对南黄海的B10岩芯进行了高密度的孢粉分析,划分出8个孢粉带,并结合~(14)C测年和浅地层剖面资料,对该孔所记录的自晚更新世末期以来的气候和环境变化进行探讨,得出如下结论:(1)植被演替过程为含阔叶树的针叶林-草原→针、阔叶混交林→以针叶树为主的针、阔叶混交林-草原→含常绿阔叶树的针、阔叶混交林→阔叶为主的针、阔叶混交林草原→含常绿阔叶树的落叶阔叶林-草地→阔叶为主的针、阔叶混交林草原→含常绿阔叶树的针、阔叶混交林;(2)气候变化历史为冷干→温湿→冷干→暖干→温湿→热干→温干→暖干;(3)沉积环境由陆相→滨海相→陆相→滨岸-浅海相;(4)黄海暖流在早全新世便已形成,而非形成于大暖期。
Based on the high density sporopollen analysis of B10 core in the South Yellow Sea, eight sporopollen zones were identified and combined with ~ (14) C dating and shallow stratum profile data. The boreholes recorded from late Pleistocene (1) The succession process of vegetation is coniferous forest with broad-leaved tree-steppe → needle and broad-leaved mixed forest → needles dominated by coniferous forest, broad-leaved mixed forest- Grassland → needle with evergreen broad-leaved tree, broad-leaved mixed forest → broadleaf-dominated needle and broadleaf mixed forest steppe → deciduous broad-leaved forest with evergreen broad-leaved tree-grassland → broadleaf-dominated needle-broadleaf mixed forest Grassland → acacia and broad-leaved mixed forest containing evergreen broad-leaved tree; (2) history of climate change: cold and dry → warm and humid → cold and dry → warm and dry → warm and humid → hot and dry → warm and dry → warm and dry; (3) sedimentary environment From continental facies → coastal facies → continental facies → coastal-shallow marine facies; (4) the Yellow Sea warm current formed in the early Holocene, rather than formed in the Great Warm Period.
