天全县光叶蕨资源现状调查与保护对策研讨

Discussion on Investigations of the Present Status of Cystoathyrium Chinensis Resources in Tianquan and Protecton Measures

  • 摘要: 在天全县通过全县普查,确定了光叶蕨现有的分布位置;对现有区域开展样线、样方和生境3个方面的重点调查,弄清现有光叶蕨主要分布在二郎山团牛坪西沟两侧的岩壁上,具有分布狭窄,数量稀少,生境特殊,自身繁殖更新能力差的特点。而导致光叶蕨濒危的原因主要表现为自身存在许多生物学缺陷,对生存环境要求苛刻,种间竞争能力低下等方面因素。针对光叶蕨资源现状和濒危机制,提出了广泛开展保护宣传教育工作,加强现有资源的保护,迁地保护,建设光叶蕨人工种群等措施,使其达到拯救保护的目的。

     

    Abstract: All areas were investigated in Tianquan conunty to find out where Cystoathyrium chinensis was scattered. By focusing on three methods of survey:line-intercept,quadrat sampling and habitat investigating,it was known that Cystoathyrium chinensis was distributed in the Tuanniuping,Erlang Mount,Tianquan County,growing at both sides of the gulch. Its main features were as follows:very narrow distribution range and extremely sparse guantity. Besides,its habitat conditions were special and biotic potential was low. The major reasons causing the endangerment of Cystoathyrium chinensis displayed the following sides:the plant itself had many biological disadvantages,the growing environmental conditions were very rigorous and its competitive ability with other species was weak,etc. Based on its resource status and endangered mechanism,some appropriate suggestions were proposed like initiating widely propaganda and educational work,strengthening the protection of existing resource,off-site preservation,and building extremely small population of Cystoathyrium chinensis,etc,to protect it.
