| 摘 要： | 水杉为我国一级保护的珍贵树种,具有重要的科研价值和应用价值。由于人类过度开发,天然水杉林生境退化严重,自然更新不良。笔者应用Braun-Blanquet的植被社会学研究方法对湖北利川钢厂湾、邓家湾、游家湾3处的天然水杉林进行群落学调查,结果表明:钢厂湾的水杉样地群落类型为水杉-尾叶山茶-日本金星蕨群落,共有植物种类约78种;邓家湾的水杉样地群落类型为水杉-桂竹-黄金凤群落,共有植物种类约81种;游家湾的水杉样地群落类型为水杉-微毛柃-大叶金腰群落,共有植物种类约58种。经过20a的演替,天然水杉林各层的盖度都逐渐增加。在种类组成上,乔木层阳性树种减少,灌木层和草本层种类组成变化不大。 |
