【摘要】 通过对台湾岛以东(角点坐标为22°N,122°E;22°N,124°30′E;24°N,125°25′E;24°N,122°E)海域67个表层沉积物样品的微体生物化石的研究,鉴定放射虫2目34科101属,178种(含21个未定种),其中泡沫虫目19科70属134种,罩笼虫目15科31属44种。对样品中保存的有孔虫化石亦进行了分析,并初步认为:影响该区微体生物化石分布的主要因素是温度、盐度、海水深度、海底沉积物、海底地形以及海流、水团等。对上述诸因素与微体生物间的关系进行了探讨。更多还原

【Abstract】 In this paper, the microfossils in 67 surface sediment samples from the sea area east of Taiwan Island are studied, two orders, 34 families, 101 genera, 178 species of radiolarian (including 19 families, 31 genera, 134 species of spumellaria and 15 families, 31 genera, 44 species of nasellaria) are identified, and the foraminifera microfossils in the sediment samples are also analysed. It is shown from the analysis results that the main factors affecting the microfossil distributions in the area are water temperature, salinity, water depth, bottom sediment, bottom topography, current and water mass. The relationships of microfossils to above factors are also discussed.更多还原
