【摘要】 作者对珠江口底质沉积的209个样品进行了分析鉴定,结果共有腋结壳有孔虫14属28种。按其分布范围不同可分为两个组合:Ⅰ.福尔摩砂杆虫Ammobaculites formosensis与卡纳利拟单栏虫Haplophragmoides canaricsnlis组合;Ⅱ.叶状串珠虫Textularia foliacea与节房双串虫Bigenerina nodosaria组合。这些组合的分布与水深,盐度、底质沉积物及pH值的关系密切。更多还原

【Abstract】 The paper discusses mainly the distribution of agglutinated foraminifera. Based on the results of quantitative and qualitative analyses, the distribution of 28 species of agglutinated foraminifera belonging to 14 genera is discussed.According to their depth distribution, two major assemblages are recognized:Ⅰ. Ammobaculites formosensis-Haplophragmoides canariensis assemblage occurring in the river estuary (the inner part of the island) with water depth less than 10m.Ⅱ. Textularia foliacea-Bigcnerina nodosaria assemblage inhabiting the outer part of the island with water depth of 10-30 m.The relationships between the distribution pattern of agglutinated foraminifera and the environmental factors, such as water, depth salinity, temperature, pH value, and the bottom of sediments are discussed.It seems that water depth, salinity, pH valu, and the bottom of sediments are more important controlling factors.更多还原
