摘　　要：通过野外实地调查对海南省万宁市大洲岛的海杧果群落特征及其物种多样性进行研究,以期为海杧果的种质保护、海防林物种的合理搭配及红树林生态恢复提供参考。结果表明:调查样方内有维管束植物62种,隶属于37科58属。乔木层的优势种为海杧果,重要值为36.45%;灌木层的优势种为矮紫金牛,重要值为8.31%;草本层的优势种为观音草,重要值为25.53%。种子植物区系成分以热带成分占优势,泛热带分布的科属最多,分别为27科、17属。群落物种丰富度Margalef指数、Shannon-Wiener指数、均匀度Pielou指数排序均为灌木层>乔木层>草本层,优势度Simpson指数为灌木层>草本层>乔木层。本调查明确了大洲岛海杧果群落的伴生物种及该群落特征,可为红树林生态恢复及海防林建设提供参考。In this study,the features and species diversity of the Cerbera manghas communities in Dazhou Island,Wanning,Hainan were studied based on field investigation,in order to provide references for the germplasm conservation,the reasonable matching of coast shelter-forest species and the ecological restoration of mangrove forest.There were 62 species in 58 genera and 37 families of vascular plants in the quadrats.Cerbera manghas,Ardisia humilis,and Peristrophe bivalvis occupied the predominant position in the tree layer(36.45%of Importance Value(IV)),shrub layer(8.31%of IV)and herb layer(25.53%of IV)respectively.Flora of seed plant was dominant with tropic zone.The pantropic type was the most widely distributed form,with 27 families and 17 genera.The Margalef’s index,Shannon-Wiener index and Pielou’s index order of all layers in the community was shrub layer>tree layer>herb layer.The pattern of the Simpson index was shrub layer>herb layer>tree layer.
