以定性与定量相结合的研究方法,对内蒙古准格尔旗晚石炭世—早二叠世早期的腕足类物种多样性、沉积环境进行了综合研究,指出本区海进序列的腕足类物种多样性远高于海退序列;规模较大、具有一定水深的海进序列是腕足类辐射、分异、物种多样性升高的重要环境体系;本区腕足类辐射起步于晚石炭世早期之初,物种多样性出现了3次峰值(晚石炭世早期之中期、晚石炭世早期之晚期、晚石炭世晚期之中期),其中晚石炭世早期之晚期是本区腕足类物种多样性的顶峰期。
Based on the qualitative and quantitative methods, the author comprehensively studied the species diversity and sedimentary environment of brachiopods in the Late Carboniferous and Early Permian in Jungar Banner, Inner Mongolia, and pointed out that there are many species of brachiopods Which is far higher than that of the regression. The large-scale marine sequence with a certain water depth is an important environmental system of the radiation and differentiation of brachiopods and the increase of species diversity. The brachiopods radiation in this area started at the beginning of the Late Carboniferous, There were three peaks in the species diversity (mid-late Early Carboniferous, late Late Carboniferous and middle Late Late Carboniferous), of which the late Late Carboniferous was the pinnacle of species diversity of brachiopods.
