Based on 18 boxes of fossil specimens collected by the author from Xiaheyan, Zhongwei, Ningxia Hui Minority Autonomous Region and some other geological and palaeontological data from both Xiaheyan and the adjacent sections in the east sector of North Qilian Mountains, the present paper studies the botanical characteristics of Middel-Late Namurian Flora in Locality Xiaheyan and represents the primary reconstruction of the Middle-Late Namurian Flora in the Northeast Qilian Mountains, also tries to make available accounts for the correlation between the different Flora provinces, and discusses the origin time of Cathaysian Flora based on the succession and the transmissibility of the plants through the whole Namurian stage.

结合自从大学三年级一直到硕士研究生阶段笔者踏勘过的北祁连山东段地区十几条石炭系剖面，以及对相关文献的整理，笔者初步分析了北祁连山东段纳缪尔中晚期植物群的垂直演化分布情况，并完成了该期全球不同植物地理区系植物群植物学性质方面的简要比较。北祁连山东段地区纳缪尔早期与中晚期植物群的遗传性与继承性，加之华夏植物群的特征分子及一些东方型地方性分子在纳缪尔早期的出现，笔者认为这些无疑为晚古生代四大植物群之一的华夏植物群的起源完成于纳缪尔初期提供了有利证据。
