摘要
对东海表层沉积硅藻分析研究 ,共发现有 10 3种和变种 ,根据其中分布特征和规律 ,结合因子负荷变化曲线 ,把东海表层沉积划分为六个硅藻组合和分布区 ,并探讨影响硅藻分布的环境因素 。
The diatom assemblages in surface sediment in the East China Sea have been studied systematically and 103 species and varieties of diatom are found. According to the characteristics and the pattern of distribution, as well as the curve of factor charge, 6 diatom assemblages and distribution zones have been recognized in the surface sediment in the East China Sea. The environment factors infecting diatom distribution are discussed. It supplies scientific support for the reconstruction of paleoenvironment.
