| 摘 要： | 介绍了内蒙古准格尔旗对臼沟本溪组含腕足动物地层，对该地区本溪组腕足动物群和性质特点进行了分析。并在识别腕足动物群落的基础上，从种的分异度，种的相对丰度，群落空间分布与能量分配等角度探讨了该腕足动物群落的一些结构模式，指出Ｅｃｈｉｎｏｃｏｃｈｕｓ ｅｌｅｇａｎｓ－Ｏｈｏｒｉｓｔｉｔｅｓ ｗｅｉｎｉｎｇｅｎｓｉｓ腕足动物群落已基本属于演替阶段中的顶极群落。

| Abstract: | Benxi Formation in Duijiugou, Jungar Banner, Inner Mongolia is described and the brachiopod fauna from the formation is carefully analysed. Having recognize d several brachiopod dominated community, we further discuss the structure of the community, such as the differentiation of species, the relative abundance of species, the spatial gradation of community and the distribution of energy et c. The brachiopod community is a peak community in the succession. |
