摘要
在舟山海岛进行柃木生境地群落学调查,分析其生境地群落树种组成和群落结构,研究柃木在舟山群岛不同区域的分布特点。结果表明:柃木生境地群落可划分为乔木群落和灌木群落;灌木群落主要只有2种植被类型:柃木—菝葜(Smilax china)—里白(Hicriopteris glauca)—金星蕨(Parathelypteris glanduligera)、柃木—白栎(Quercus fabri)—檵木(Loropetalum chinensis)—菝葜—淡竹叶(Lophatherum gracile),而乔木群落层次明显,并且还有层间层植物;舟山群岛不同区域柃木群落中植物较为丰富,共有223种58科142属;不同区域柃木群落中植物种类也按照从南到北的干湿度梯度,沿普陀、定海、岱山、嵊泗一线递减。
Investigations were implemented on distribution characters and species composition and community structure of Eurya japonica in Zhoushan,Zhejiang province.The result demonstrated that different communities could be divided into arbor and shrub types.Shrub communities had two vegetation types:E.japonica-Smilax china-Hicriopteris glauca-Parathelypteris glanduligera,and E.japonica-Quercus fabri-Loropetalum chinensis-S.china-Lophatherum gracile.Arbor communities had evident layers with interlayer plants.Communities of E.japonica in different districts are rich in plant species.The investigation showed that there are 223 species of plants belonging to 142 genera and 58 families.Plant species decreased in E.japonica communities from south to north.
