摘要
通过对冲绳海槽南部４６个站位表层沉积物中的放射虫研究，初步鉴定９６个种，其中泡沫虫目在种和个体数量上均占绝对优势．与国内外有关资料对照，冲绳海相南部表层沉积物中的放射虫组合属热带暖水动物群．根据定量统计资料，将表层沉积物中的放射虫分成四个分布区，探讨了沉积物类型、沉积物化学性质、海水温度、盐度、深度以及海流等环境因素对放射虫数量分布的影响．
Radiolarians and their distribution from the surface sediments in southern Okinawa Trough of the East China Sea are reported for the first time.Based on the analysis of radiolarians from the surface sediments of 46 stations, 96 species were indentified, of which spumellaria is dominant in the numbers of species and individuals. Compared with relative data, the radiolarian assemblage from southern Okinawa Trough of the East China Sea is regarded as the tropical warm water fauna. According to the quantitative statistical data four quantitative distribution regions were distinguished. And the influences of the sediment types,sediment chemical natures, temperature, salinity, depth and ocean currents on the quantitative distribution were discussed.
