| 摘 要： | 祁连山北麓石炭纪植物化石,可概括为六个组合:大体相当于杜内期、维宪期、纳缪尔早期、纳缪尔中晚期、维斯发期和斯特凡期。在维宪期与纳缪尔早期、纳缪尔早期与中晚期之间,植物组份有较明显的变化。华夏植物群的最初出现,可能从纳缪尔中期就已开始。

| Abstract: | Summing up the studies on the Carboniferous plant fossils along the northern slope of the Qilianshan Mountains, six floral assemblage zones may be divided. They correspond approximately to the Tournaisian, Visean,Early Namurian, Middle-Late Namurian, Westphalian and Stephanian, respectively. Two obvious floral changes took place: one is between the Visean and Middle-Late Namurian. The first appearance of the Cathaysia flora seems to occur from the Namurian B. |
