世界上有关河口区有孔虫群的研究已有百年以上的历史,国外已有近40条河口的工作记录,我国近十几年来也已开始研究.关于珠江口底质沉积中有孔虫的系统工作,迄今尚无报道,同济大学(1980)对本区西江口的有孔虫和介形虫群做了较详细的研究,并划分出霜粒企虫-毕克卷转虫组合和同现卷转虫-条纹判草虫组合.H.O.Waller(1960)对台湾岛以南到北部湾的沿海陆架的底质有孔虫群建立了四个组合,其中内陆架组合(20—46m)为异地企虫-日本九字虫组合.本文的工作是在上述基础上进行的.
The research on the foraminiferal flora in estuaries in the world has a history of more than 100 years and the work record of nearly 40 estuaries in foreign countries has been recorded in our country. In the past decade or so, China has also started to study the foraminifera Systematic work has not been reported so far. Tongji University (1980) made a more detailed study on the foraminifera and ostracod swarms in the Xijiangkou of this area, and classified the coleoptile assemblages and co-occurrences (1990) established four combinations of foraminiferal foraminifera on the coastal shelf south of Taiwan Island and Beibu Gulf, of which the continental shelf combination (20-46 m) Entomological - Japanese nine-character insects combination.The work of this paper is based on the above.
