对东海南部陆缘莆田、泉州地区两口钻井岩芯系统的沉积硅藻研究，共发现33属117种（或变种）硅藻化石，根据剖面硅藻组合特征的变化，结合计算机的对应分析结果划分了硅藻带，建立该区全新世的7个硅藻组合序列，恢复当时古环境演变的7个阶段，填补该区沉积硅藻系统研究的空白，丰富了海陆过渡沉积硅藻的研究。

[Abstract]
The diatoms lound from the Holocene sediments of 2 well's cores in Putian and Quanzhou areas of the East China Sea have been systimatically researched, and 117 species and varities in 33 genus identified. 7 diatom zones have been divided according to the characteristics of the diatom assemblages and computerised corresponding analyses,and 7 stages of paleoenvironmental evolvement are reconstructed.The results supply the gap of systimatical study of diatoms in sediments of the areas and enrich the study of diatoms in sediments of the continent marine margin.
