| 摘 要： | 随着全球变化等环境演变和预测问题研究的深入开展,要求有孔虫研究提供更准确的定量信息.丰度是有孔虫定量研究中最基本、最重要的参数之一.本文在总结前人大量工作基础上,结合作者近年野外调查和室内研究工作中的一些发现,试图对影响有孔虫丰度的生态因素进行较全面的剖折.认为食物、理化条件和海洋污染等生态因素是控制有孔虫生产量乃至丰度的基本原因.综合考虑这些因素有助于环境定量解释更臻准确.

| Abstract: | Foraminiferal abundance is one of the most important data in quantitative foraminiferal research. There are, however.various factors controlling foraminiferal abundance of sediments. They are of ecology and non-ecology. In thia paper, the author made a reconsideration of ecological factors, including food conitions,predation, reproduction, symbiont, migration, physical-chemical parameters, and marine pollution. These factors interact among themselves. Comprehensive consideration of them is helpful to improve paleo-environmental reconstruction. |
