摘要
在简述蕨类植物系统发生关系、传统分类系统与基于分子系统学的现代分类系统的基础上,概述了中国蕨类植物区系地理研究的现状及最新进展,并对今后的研究工作进行了展望。根据分子系统学研究,传统的蕨类植物门以及一些蕨类植物类群并不是自然类群。中国蕨类植物区系及分布的基本规律是东南多、西北少,华南、西南极为丰富,西南地区是许多温带属的分布中心。分析了中国蕨类植物区系研究的主要问题,指出关于蕨类植物在生态系统中发挥的作用,特殊生境研究、数值分析方法在蕨类区系地理中的应用,区系地理学与其他学科的交叉是今后可能的热点与亟待加强的几个领域。
After brief introduction of the phytogenetic relationships of pteridophytes, we summarized the tra ditional classification system and system based on modern molecular systematics,current situation and new progress as well as future study expectation of floristic geography of the pteridophytes in China in the paper. The results of molecular phylogeny showed that the pteridophyta and some groups are not natural groups. The diversity of the floras and distribution in ferns in southeast China is abundant, while northwest is less. The diversity of the south and southwest China is extraordinarily rich,and the distribution center of many temperate genera is the southwest China. The main issues of flora of pteridophytes in China were an alyzed here, and the effect of ferns in ecosystem, the study of special habitat, the application of numerical analysis in ferns＇ floras study,and the intersect between floristie geography and other related subjects could be hot topics and areas needed toreinforce in the future.
