摘　　要：通过样方法和样线法对大兔屿进行植物资源调查,其主要的植被类型是亚热带常绿阔叶林、灌草丛。有维管植物69科,139属,152种。蕨类3科,3属,3种;裸子植物3科,3属,3种;被子植物63科,133属,146种。乔木20科,27属,30种;灌木31科,44属,46种,草本和藤本30科,68属,74种。其中,原生植物125种,外来植物27种,入侵植物10种,无珍稀濒危植物。植被群落的植物区系组成中,属的分析表明,大兔屿植物以热带、亚热带成分为主。种子植物属划分为12个分布区类型及其变型,其中成分最多的是泛热带分布及其变型,为区系总数的35.29%。群落以高位芽植物占主要优势,为46.71%。人工栽培的台湾相思林、马尾松林及木麻黄林总的覆盖率却高达80%。最后针对海岛特色景观的营造,对大兔屿植物资源的保护和利用提出相关的建议。The main vegetation types in Datu Island are the subtropical evergreen broad leaved forest,shrub and grass.There are 69 families,139genera and 152 species of vascular plants in this island.Including 3families,3genera,3species of ferns;63families,133 genera,146species of Angiosperms.20 families,27genera,30 species of trees;31families,44 genera,46species of shrubs,30 families,68genera,74 species of herbs and vines.Among them,125 species are endemic plants,27 species are exotic plants,10 species are invasive plants,no rare and endangered plants.The analysis of the flora composition of the vegetation communities showed that the main components were the tropical and subtropical areas.Seed plants are divided into 12 distribution types and variants,which the largest component is the pan tropical distribution and its variants,up to 35.29% of the total.The main community mainly dominant by phanerophyte,for 46.71%.The total coverage of artificial cultivation about Acacia confusaforest,Pinus massonianaand Casuarina equisetifoliaforest isas high as 80%.Suggestions were also put forward to the protection and utilization of the plant resources to the construction of characteristic landscape of islands.
