摘　　要：物种的分布及其种群所属生态系统中生物多样性特征是研究生物地理学、生态学习性基础内容,是评估珍稀濒危和制定保护策略的重要支撑。桫椤科(Cyatheaceae)植物是珍稀濒危、孑遗植物,具有较高的科研价值、药用价值、观赏价值,受国内外研究者的关注较多。本文在概述桫椤生物学、生态学研究的基础上,从生物地理学、系统进化学、分子遗传学、植物生态学和植物资源学等多学科交叉、多角度聚焦桫椤科植物的分布、分类、生物多样性和生态特性新研究成果,梳理桫椤遗传多样性、群落物种多样性、所属生态系统多样性特征,总结已有研究中未解决问题,提出未来需要关注桫椤科植物生物地理学、生态学研究方向。The distribution of species and the characteristics of biodiversity in the ecosystem are the actual contents of biogeography and ecological habit.It is also essential to support the assessment of rare and endangered species and the formulation of species conservation strategies.Cyatheaceae are rare,endangered,and relict plants and have been paid more attention by domestic and foreign researchers that have high scientific research,medicinal and ornamental value.Based on the research on the biology and ecology of Cyatheaceae,this paper focused on the new research achievements on the distribution,classification,biodiversity,and ecological characteristics of Cyatheaceae from multi-disciplinary and multi-angle,such as biogeography,systematic evolution,molecular genetics,plant ecology and plant resources and other disciplines.It combed the characteristics of genetic diversity,community species diversity,and ecosystem diversity of Cyatheaceae,and summarized the unsolved problems in the existing research.It was proposed that future research should focus on the directions of Cyatheaceae plant biogeography and ecology.
