摘    要:通过调查野生钟花樱典型群落,分析了群落物种的组成、物种的生活型、频度分布规律与多样性指数,对群落的外貌和垂直结构及群落类型作了分析.结果表明:野生钟花樱群落木本植物组成有110种,隶属于41科.低频度、单属种植物较多,物种分布不均匀,植被分化和演化的趋势较大.钟花樱多生长在干扰后的林地或林缘,随着群落的自然演化有被其他物种替代的可能.适度干扰、开辟林窗有利于钟花樱的天然繁衍.

关 键 词:钟花樱  群落特征  物种多样性

Abstract:Based on the field investigation into the typical sample plots of Cerasus cerasoides var.campanulata, the species composition,life-form,relative frequency,diversity index,community appearance,vertical structure and community types were analyzed.The results showed that there were 110 woody plant species in the community,belonging to 41 families.Among there were many species with low appearance frequency or the species belonging to single genus of some families.The species distribution was uneven,showing the trend of differentiating and succeeding.It was showed that most Cerasus cerasoides var.campanulata mainly grew in the disturbed sparse woods or at the forest edges,and there was possibility that it would be substituted by other species in the evolution process.It was suggested that moderate disturbance and artificial forest gaps be beneficial to the reproduction of Cerasus cerasoides var.campanulata.
Keywords:Cerasus cerasoides var.campanulata  community characteristics  species diversity
