The single-celled phytoplankton included 116 inshore wide distribution species, 31 inshore warm-water species and 26 inshore temperate species, and the vascular plants were of 6 ecological groups, i.e., halophtes (24 species), hydrophtes (22 species), amphiphytes (35 species ), mesopllytes (103 species), zerophytes (6 species), and psammons (4 species). Halophtes, hydrophtes, and amphiphytes were the edificators and dominants, reflecting the azonal feature of the wetland vegetations. The vascular plants were divided into 5 life-forms, including 20 phaenerophytes, 4 chamaephytes, 54 hemicryptophytes, 48 geophytes and 68 therophytes, among which, hemicryptophytes and geophytes accounted for 52.58%, reflecting the relatively important function of cold and wet climate and local water-accumulated bottomland environment on the vascular flora formation.

On longitude gradient, from east to west, there is a slight trend of diversity of Lauraceae plants, and no obvious trend was observed on specification strength. In general, the distribution center of Lauraceae plants is in the southern part of the study area with low latitude and altitude(elevation 1500-2000 m or so).

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。

One hundred and thirty four families, 578 genera and 1197 species are recorded in this area. According to the information of historical geology and natural conditions, the composition of seed plant flora and the areal-types of genera were analyzed. The results showed that its origin was rather ancient and its geographical compositions were complicated. There were many species of rare and endangered plants, e.g. Taxus chinensis var. mairei, Bretschneidera sinensis, Emmenopterys henryi, Fokienia hodginsii, Torreya grandis, Phoebe bournei, Ormosia henryi, and so on. Most of these plants had high value in economics and scientific research. According to statistics and analysis of genera in the present flora, 578 genera were divided into 14 areal-types. The ratio of tropical and temperate genera was respectively 48.6% and 49.2%, so its flora was characterized by transitional floristic elements, and in wide connection with the world.
