| 摘要: |
| 我国兜兰属Paphiopedilum种质资源十分丰富，已知拥有34种原产种，其中云南和广西等省区是其主要分布区域。兜兰属植物因花型奇特、观赏价值高而广受青睐，但其长期以来面临过度采挖、栖息地破坏、种群退化等多重威胁，导致部分物种野生种群数量急剧下降，遗传多样性受到不同程度削弱。除带叶兜兰Paphiopedilum hirsutissimum和硬叶兜兰P.micranthum被列为国家二级重点保护植物外，其他兜兰属植物均被列为国家一级重点保护野生植物。在此背景下，兜兰属植物的生理生态特性、保护遗传学及系统发育研究日益受到关注。本文综述了十余年来相关领域的研究进展，系统梳理了当前取得的成果与存在的问题，提出了未来研究方向与建议，以期为兜兰属植物保护策略的制定和后续研究提供科学参考。 |

| Abstract: |
| Paphiopedilum has rich germplasm resources in China,and 34 Paphiopedilum species are known to be native to China.The regions such as Yunnan and Guangxi are the main distribution areas of Paphiopedilum in China.Paphiopedilum species are widely valued for their distinctive floral morphology and high ornamental appeal.Nevertheless,prolonged exposure to multiple threats,including overexploitation,habitat destruction,and population degradation,has resulted in a drastic decline of wild populations of certain species and a corresponding reduction in genetic diversity at varying levels.It should be noted that Paphiopedilum hirsutissimum and P.micranthum are listed as national second-class key protected plants,while other Paphiopedilum species are classified under the category of national first-class key protected wild plants in China.Against this backdrop,increasing attention has been directed toward the research on the ecophysiology,conservation genetics,and phylogeny of Paphiopedilum species.This review summarizes the research progress achieved over the past decade,systematically synthesizes current findings and existing challenges,and proposes future research directions and recommendations,aiming to provide a scientific basis for the development of conservation strategies and further studies on Paphiopedilum. |
