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.
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。
Such standard distribution is proposed based on the ecological cha racter of the coccolithopora.
以工作区南黄海辐射沙洲海区为例，探讨了颗石的滨浅海环境中的标准分布，并以这种标准分布模式为基础，通过工作区采集的大量样品，得出该海区各主要潮流深槽及沙脊的沉积特征。
