“男生女生一起相差差差轮滑鞋,免费游戏”濒危物种紫毛兜兰男生女生一起相差差差轮滑鞋,免费游戏在广西花坪保护区重现

  中新男生女生一起相差差差轮滑鞋,免费游戏网桂林11月18日电 (李双男生女生一起相差差差轮滑鞋,免费游戏林 马敏)广西林业部门18日介绍,近日,广西花坪国家级自然保护区在开展综合科学考察工作时,再次发现珍稀濒危物种、国家一级保护植物紫毛兜兰种群50余丛(株)。

  据保护区工作人员介绍,2006年花坪保护区开展综合科学考察期间,广西植物研究所科研团队首次发现紫毛兜兰,花坪保护区是紫毛兜兰在广西唯一已知的分布点。2008年我国南方遭遇严重雨雪冰冻灾害时,花坪保护区内的紫毛兜兰遭受毁灭性灾难。在近期的考察中,花坪保护区的紫毛兜兰种群再次被发现,但仍未恢复到受灾前的规模。

  紫毛兜兰叶碧绿,花期长,花型奇特,花带金黄色泽,仪态雍容华贵。尤其是附生于大树或崖壁上的紫毛兜兰,花开时节常构成空中花园奇观,具有较高的观赏价值。

  紫毛兜兰生长习性偏热带,对环境要求十分苛刻。花坪保护区地处中亚热带,出现紫毛兜兰极为罕见。紫毛兜兰选择花坪保护区作为“落脚点”,对研究兜兰属植物区系地理学具有重要学术价值。(完)
