浙江天台山七子花群落研究

Heptacodium miconioides, fine trees for flowers tending,are precious and rare ones,and are on the verge of extinction.This paper analyzes the community characteristics and quality of the Heptacodium miconioides forest distributed in the Tiantai Mountains of Zhejiang Province. The vertical structure of Heptacodium miconioides is rather complicated.It can be divided into arborous layer,shrub layer,herbaceous layer and interstratum plants which are numerous in quantity.The community has an outstanding dominant species and the arborous layer possesses a comparatively high diversity index.The similarity is rather striking among different quadrats species. The Heptacodium miconioides community is at a declining stage,and the distribution pattern of the community shows a clump.
