| 摘 要： | 南海北部ＨＹ４－９０１孔沉积连续、粒度均匀，浮游有孔虫丰富，共鉴定１０属２６种，其中以暖水种占优势，凉水种也有相当含量。浮游有孔虫组合的研究表明，本区的溶解作用不强，不是影响ＣａＣＯ＿３分布的主要因素。全新世的气温变化，可以分为五期：１）迅速升温期，２）高温期，３）降温期，４）温暖期，５）温凉期。

| Abstract: | There are abundant planktonic foraminifera in Piston core HY4-901,which is characterized by continual and even-textured sedimentation,bored from the northern slope of the South China Sea.Among the 26 species identified as belonging to 10 genera,most of them are characteristic of warm waters,with a few indicating cool waters.Results of our analysis show that dissolution of planktonic foraminifera was by no means the main factor controlling the distribution of CaCO3 and that their distribution trends suggest 5 phases of climatic changes during the Holocene. |
