摘要
对渤海西部近海5个钻孔的沉积物作了孢粉和藻类分析研究。渤海西部海域全新世孢粉组合可划分出三个孢粉带,反映了不同的气候时代。(1)Artemisia—Chenopodiceae—Pinus孢粉组合带,反映了温暖略干气候——北方期:(2)Pinus—Chenopodiaceae—Artemisia—Quercus孢粉组合带,反映了温湿气候——亚北方期:(3)Chenopodiaceae—Artemisia—Pinus—Quercus孢粉组合带,反映了温干气候——亚大西洋期;渤海西岸近海全新世和晚更新世的界限约在10000年左右。
A study on the palynology of the Holocene sediments from five cores under coastal waters of the western Bohai Sea has been conducted since 1983. Distributing over a wide range under the coastal waters, the palynological assemblages, only slightly differing from each other, have obviouse common characteristics and can be divided into three spore and pollen zones which represent different climatic epochs. The lower limit of Holocene in the concerned region is also discussed in this paper; it is dated about 10 000 B.P.
