| 摘 要： | 依据化石的层位分布和组成内容，登封二叠纪煤系地层植物群由下而上可划分为三个植物化石组合带：１．早二叠世中期山西组Ｅｍｐｌｅｃｔｏｐｔｅｒｉｓｔｒｉａｎｇｕｌａｒｉｓ－Ｔａｅｎｉｏｐｔｅｒｉｓｍｕｌｔｉｎｅｒｖｉｓａｓ－ｓｅｍｂｌａｇｅｚｏｎｅ；２．早二叠世晚期下石盒子组Ｇｉｇａｎｔｏｐｔｅｒｉｓｎｉｃｏｔｉａｎａｅｆｏｌｉａ－Ｃｈｉｒｏｐｔｅｒｉｓｒｅｎｉｆｏｒｍｉｓａｓｓｅｍｂｌａｇｅｚｏｎｅ；３．晚二叠世早期上石盒子组Ｌｏｂａｔａｎｎｕｌａｒｉａｈｅｉａｎｅｎｓｉｓ－Ｐｔｅｒｏｐｈｙｌｌｕｍｅｒａｔｕｍａｓ－ｓｅｍｂｌａｇｅｚｏｎｅ。另外，文中还讨论了这些植物组合的主要特点

| Abstract: | On the bases of both the stratigraphical distribution and the floral composition,the plants in the Permian coal measures strata of the Dengfeng district,western Henan can be divided into three megafloral assemblage zones as follows: 1 Emplectopteris triangularis-Taeniopteris multinervis assemblage zone.It belongs to the middle stage of Early Permian,approximately representing the floral aspects of the Shanxi Formation. 2 Gigantopteris nicotianaefolia-Chiropteris reniformis assemblage zone.It belongs to the late stage of Early Permian,including the fossil plants of the Lower Shihezi Formation. 3 Lobatannularia heianensis-Pterophyllum eratum assemblage zone,which blongs to the early stage of Late Permian and represents the floral aspects of the Upper Shihezi Formation. In addition,the main floral characteristics of each assemblage zone are briefly disscussed. |
