| 摘 要： | 将沉积物中的颗石作为一种特殊的沉积颗粒 ,根据颗石藻的生态特点 ,建立了海岸带环境中颗石丰度与水深关系的标准分布模式。以此模式为依据 ,通过对柱状样品中颗石的研究 ,确定了工作区近 3 .5万 a以来古水深的变化规律及变化幅度 ,为海面变化的研究提供了定量的水深资料。

| Abstract: | Coccolith index distribution pattern(the relationship between coccolith abundance and water depth)in submarine sand ridges of the south Yellow Sea is built up based on the coccolithophore ecological character.According to the pattern,the former water depth and its changes during the latest 35 thousand years are obtained in the light of coccolith distribution in the SMK core,this provides a new method in quantitative study of former water depth. |
