中国青藓科植物分类及系统研究

Brachytheciaceae is an important large family of Pleurocarpous mosses. The range of Brachytheciaceae always changed, and there have been different opinions on it all over the world. Thus this project aimed at studying morphology, geographic distribution, submicroscopical structure of the spores, cytological characters of its argumentative genera and species. Some scientific names were emended. Therefore, 3 genera remote from Brachytheciaceae were exluded from it and transferred to the coherent family, and we proposed the scientific and reasonable limitation to the range of Chinese Brachytheciaceae , theoretically and practically.

. 青藓科是侧蒴藓类中较大的一个类群。在我国种类十分丰富，主要分布于东北、西北和华北地区。一百多年来，苔藓学家对此科的分类有很大的分歧，主要是与邻近科的分类界线及本科属间的关系。本项目拟用细胞学、形态解剖学、细胞核型分类、数值分类及电镜扫描技术，结合传统的分类方法，对本科相关的属进行比较研究，综合分析。在此基础上提出青藓科与邻近科及本科属间的自然分类系统。
