| 摘 要： | 定量分析了南海３３个１０００ｍ水深线以内的现代表层沉积样品中的硅藻，发现主要的种有菱形海线藻Ｔｈａｌａｓｓｉｏｎｅｍａｎｉｔｚｓｃｈｉｏｉｄｅｓ、短刺角毛藻Ｃｈａｅｔｏｃｅｒｏｓｍｅｓｓａｎｅｎｓｉｓ、结节圆筛藻Ｃｏｓｃｉｎｏｄｉｓｃｕｓｎｏｄｕｌｉｆｅｒ、长海毛藻Ｔｈａｌａｓｓｉｏｔｈｒｉｘｌｏｎｇｉｓｓｉｍａ、海洋菱形藻Ｎｉｔｚｓｃｈｉａｍａｒｉｎａ和条纹小环藻Ｃｙｃｌｏｔｅｌｌａｓｔｒｉａｔａ。根据硅藻主要种的百分含量、各站位硅藻丰度的变化以及其它一些特征，将３３个样品划分为５个硅藻组合，并着重研究这些组合与环境因素之间的关系。

| Abstract: | it is found that Thalassionema nitzschioides, Chaetoceros messanensis,Coscinodiscus nodulifer, Thalassiothrix longissima, Nitzschia marina and Cyclotellastriata are important diatom species by quantitative analysis on 33 surface sedimentsamples within 1 000m isobath of the South China Sea. According to the percentagesof important species, diatom individual numbers and other characteristics, 33 samplesare divided into 5 assemblages and their relations with environmental factors arediscussed emphatically, |
