摘　　要：独叶草Kingdonia uniflora Balfourf.et W. W. Smith是我国特有的单种属植物,也是国家一级重点保护植物。为了探讨人为干扰对独叶草生长的影响,我们在陕西省太白山下板寺至上板寺设置样方,对生境完全遭受破坏和无破坏两种条件下独叶草根状茎生长情况进行了比较研究。结果表明:人为破坏的环境下独叶草根状茎长度较短、年生长长度也较短,其生长状况受到影响,生境的破坏是独叶草致濒的原因之一。Kingdonia uniflora is an endangered and a monotypic genus endemic to China.In the present paper,the length of rhizome and annual rhizome of K.uniflora under the destroyed and no disturbed habitat was comparatively studied.The results showed that the length of rhizome and annual rhizome are much shorter in distroyed habitat than in no disturbed habitat.This result indicates that the growth of K.uniflora is affected by the human disturbance that should be one of the endangered causes of the species.
