根据近年野外调查和室内研究，本文探讨了影响沉积物中有孔虫丰度值的诸死态因素，死态因素乃指环境对死亡后的生物体产生各种变化作用的自然因素。研究表明溶解作用和搬运作用对沉积中有孔虫丰度有极为重要的影响作用。同时，沉积作用和成岩作用也是不容忽视的影响因素。充分考虑这些因素，可使有孔虫分析为古环境研究提供更准确的定量信息 According to the field investigation and indoor research in recent years, this paper explores the factors that affect the abundance of foraminiferal sediments in the sediment. The factors of death refer to the natural factors that produce various changes in the environment after death. Studies have shown that dissolution and removal have an extremely important effect on the abundance of foraminifera in sediments. At the same time, sedimentation and diagenesis are also influential factors. Taking full account of these factors, foraminifera analysis can provide more accurate quantitative information for paleoenvironmental research
