鄂西二叠纪的有孔虫类极为丰富,几乎产于各类碳酸盐岩中。其系统演化快,地理分布广,因此对其生态环境的研究,对于恢复古海域各种沉积环境,具有较大的意义。我国对二叠纪有孔虫的研究多则重于分类学和各地层单位中有孔虫组合特征及其地层学意义方面,而对有孔虫生态还很少有系统的研究。傅瑜(1979)应用有孔虫和藻类分布特征探讨四川盆地阳新世沉积条件就是一种尝试。笔者拟从碳酸盐岩岩石学、岩相
The Permian foraminifera in western Hubei Province is extremely rich in almost all kinds of carbonate rocks. The evolution of the system is rapid and the geographical distribution is wide. Therefore, the study of its ecological environment is of great significance to restoring sedimentary environment in the ancient sea area. The study of Permian foraminifera in our country lays more emphasis on taxonomy and assemblage of foraminifera in stratigraphic units and its stratigraphic significance. However, there are seldom systematic studies on foraminiferal ecology. Fu Yu (1979) Application of distribution characteristics of foraminifer and algae to explore the sedimentary conditions in the Yangtz Formation of the Sichuan Basin is an attempt. I intend from carbonate petrology, lithofacies
