Based on a quantitative analysis of radiolarian in 80 surface-sediment samples from the northern area of Okinawa Trough, this paper reported the species composition and faunal assemblages characteristic of radiolarian, expounded the distribution pattern of radiolarian abundance and diversity in surface sediments from this area. In this paper, a preliminary study on the relation of the distribution and abundance of radiolarian to environmental factors, such as chemical and physical properties of the overlying masses (sea-surface temperature, salinity, nutrients and primary productivity) and the type and composition of sea-bed sediments was made. The radiolarian data was evaluated using a Q-mode factor analysis to identify different faunal assemblages and their geographic distributions, then the relationship between radiolarian assemblages and distribution of water masses, hydrographic boundaries such as frontal systems was analyzed. A new radiolarian-based transfer function to estimate mean-annual sea surface temperature and seasonal range were examined to test its success in the study area.

本文对冲绳海槽北部80个表层沉积样品中的放射虫进行了系统鉴定和定量统计，研究了放射虫的种类组成与类群特征以及其丰度和分异度的分布；分析了海水温度、盐度、营养盐以及沉积物类型、成分等环境因素对放射虫分布的影响；采用Q-型因子分析，求得放射虫的属种和组合分布特征，探讨了放射虫组合与不同水团、海洋水文结构之间的关系；并对Pisias（1997）建立的估计表层海水年平均温度和其变化范围的放射虫转换函数在研究区的适用性做了检验。
