摘要:
有孔虫在海洋环境指示方面具有重要意义，对现代环境中有孔虫的分布及影响因素进行研究有助于利用有孔虫对地质历史时期的沉积环境进行还原。我国南海海域辽阔，南海有孔虫的相关研究很早便有报道。对我国南海北部海域表层沉积物中的底栖有孔虫分布特征进行了描述，研究区以玻璃质壳底栖有孔虫占主导，胶结壳其次，瓷质壳最少。根据底栖有孔虫的分布特征划分了4个底栖有孔虫组合，组合1为Heterolepa subpraecincta - Hanzawaia mantaensis - Rotalinoides gaimardii；组合2为Bulimina marginate - Lagena substriata；组合3为Elphidium advenum - Pararotalia nipponica；组合4 为Recurvoides contortus - Ammodisus cretaceous - Bulimina aculeata。对影响该区域底栖有孔虫分布的环境因素进行了探究，结果表明，温度、盐度、底质类型等对底栖有孔虫的分布均存在一定程度的影响，海流对研究区底栖有孔虫时空分布的影响值得进一步探究。
Abstract:Foraminifera is an important and sensitive environment indicator. To study the distribution pattern and influencing factors of the foraminifera in the modern environment is the key to the reconstruction of sedimentary environment in the past. South China Sea covers a vast area, researches on the modern foraminifera in that part of the South China Sea have been reported since a long time. Recently, more and more researches have been devoted to the change of foraminifera and its relation to the methane leakage in the South China Sea. However, few studies have been donated to the distribution of foraminifera in the modern environment of northern South China Sea. In this study, we carefully described the distribution pattern of benthic foraminifera in the northern part of the South China Sea and discussed the factors affecting their distribution pattern. In the study area, the calcareous hyaline benthic foraminifera dominate, followed by the agglutinated benthic foraminifera and the calcareous porcelaneous benthic foraminifera. Four benthic foraminifera assemblages are recognized according to their distribution patterns, namely the assemblage 1: Heterolepa subpraecincta-Hanzawaia mantaensis- Rotalinoides gaimardii; the assemblage 2: Bulimina marginata-Lagena substriata; the assemblage 3: Elphidium advenum-Pararotalia nipponica; and the assemblage 4: Recurvoides contortus-Ammodisus cretaceous-Bulimina aculeata. Environmental factors, such as temperature, salinity, and substrate type in the northern part of the South China Sea all have influences on the distribution of benthic foraminifera to certain extent, and the influence of oceanic currents on the spatial and temporal distribution of benthic foraminifera deserves further investigation.
