小蓬竹;群落特征;优势树种;物种多样性
摘  要：
对小蓬竹Ampelocalamus luodianensis集中分布的群落进行样方调查,结果表明:小蓬竹群落中共有维管束植物100种,分属44科76属。其中含单种的属有60个,占属数的79%,说明小蓬竹群落植物的科属组成较为分散。群落中乔木层不明显,灌木层中小蓬竹重要值最大,表明该群落中以小蓬竹为主要优势树种。群落中树种组成丰富、树种重现性低而且优势树种不明显。小蓬竹平均地径与群落中植物总个体数、木本植物总个体数、群落中物种总数之间呈极显著负线性相关关系;小蓬竹平均地径与Margalef物种丰富度指数呈显著负线性相关关系。

摘  要：
According to the community investigations in the concentrated distribution area of Ampelocalamus luodianensis,it was found that there were 100 species of vascular plants in Ampelocalamus luodianensis community,which belong to 44 families and 76 genera.Of the 76 genera,the genera number only having one specie in this community was 60,accounting for 79%.,it indicates that families and genera compositions were in dispersed state in Ampelocalamus luodianensis community.The tree layer was not obvious and the importance value of Ampelocalamus luodianensis wass maximized in shrub layer,it indicates that Ampelocalamus luodianensis was the mainly dominant species.The tree species composition was abundant,the reproducibility of tree species was low and the dominant species was not obvious in Ampelocalamus luodianensis community.The average ground diameter of Ampelocalamus luodianensis had very significant negative correlation with the total individuals of plants,so did the total individuals of woody plants and the total species in community.There was significant negative correlation between the average ground diameter of Ampelocalamus luodianensis and Margalef's species richness index.
