| 摘 要： | 将福建九龙江河口平原ＺＫ５孔剖面细分为４个硅藻段、２４个硅藻带，并结合其他钻孔的微体生物组合特权和年代测定结果等进行分析。研究表明，晚玉木冰期本区海面升降频繁，但大多处于河口港湾环境，这主要是构造沉降所造成的；其间出现３次低海面，均为河流沉积环境。全新世冰后期海水大规模入侵，鼎盛期本区相对海面高出现代海面达５－１０ｍ。

| Abstract: | The diatom assemblages discerned in Core ZK5 can be grouped under 4 units,and can be subdi- vided into 24 zones. The 4 units were deposited in the Late Wurm Glacial , Early Holocene , Middle Holocene and Late Holocene,respectively. Comprehensive analysis of microbial assemblages,lithological characteristics and age determinations of ZK5 and some other boreholes,shows that during the Late Wurm Glacial the sea level of the study area rose and fell frequently,but had principally been in the environments of estuary-bay, mainly resulted from tectonic subduction. Additionally , in this period , 3 low sea levels occurred , resulting in the sedimentary environment of river. As for Holocene , sea water intruded massively and the sea level over the transgression maximum had been 5-10 m higher than that of present. |
