贵州掌叶木群落调查

Investigation of community of Handeliodendron bodinieri in Guizhou

掌叶木〔Handeliodendronbodinieri (Levl.)Rehd .〕是国家 2级重点保护植物 ,为一典型的喜钙种类 ,生长在黔桂边界海拔 4 0 0～ 10 0 0m的岩溶地带 ,在贵州则分布于荔波、独山、平塘、安龙、兴义诸县。由于人类活动的严重干扰 ,这一珍稀物种的数量已日见稀少 ,正处于濒危境地。本文系在贵州南部的平塘、荔波对掌叶木群落所作调查的总结 ,试图为其保存及引种驯化提供一定的科学依据。

In Guizhou province the species is distributed in Libo, Dushan, Pingtang, Anlong and Xingyi conuties. Because of its habitats disturbed seriously by human activities, the amount of this rare species is getting decreased and in an endangered situation.
