论荷叶铁线蕨的分布特点

ON THE DISTRIBUTION CHARACTERISTIC OF THE VARIETY ADIANTUM RENIFORME VAR. SINENSE

  • 摘要: 荷叶铁线蕨是我国近年来在四川发现的又一特有珍稀植物。仅产于万县至西沱的长江河谷。为了弄清它的分布规律,为今后更好地保护和发展这一特有珍稀植物提供科学依据,我们于1985年对该植物进行了实地考察。本文就是在此基础上分析整理而成的。作者从分析荷叶铁线蕨产地的土壤、气候、植物种类等要素入手,初步阐明了荷叶铁线蕨的分布状况及其群落特点。

     

    Abstract: The Plant A. reniforme L. var. sinense Y. X. Lin, which was found in 1978 in China, is one of the varieties which have evolved from the species A. reniforme L. in Adiantum, Adiantaceae. It is distributed in a very narrow region where belongs to the Wanxian-Xituo Changjiang valley, eastern Sichuan (between 107°50'-108°21'E., 30°20'-30°51'N.).Because the variety is a new race of the Chinese Adiantaceae and one of the endemic plants to China, it was listed in the State's Protected Plants List in 1982.In the paper author deals with the soil and climatic situation in the variety's distribution region; and analyses the constitutions of the communities which include the variety. Its distribution and main companions are expounded in the paper.
