[目的]了解大小渔山岛及其周围岛屿植被资源现状.[方法]采用样方法与路线法相结合的方法对大小渔山岛等岛屿植被资源现状进行调查,并对海岛植被资源进行区系成分分析以及地理成分分析.[结果]海岛原生植被较少,植被类型多为原始次生或人工林野化形成.天然植被中的森林植被类型较少,而灌丛、草丛和滨海植被类型占优势.植物种类较为丰富.海岛植物区系在区系地理、区系发生上与世界各地植物区系有着广泛的不同程度的联系,而且地理成分具有一定的多样性.[结论]调查结果为海岛植被资源的保护与开发提供了理论依据.%[Objective] The aim was to understand status of vegetation resources of Dayushan and Xiaoyushan and surrounding Islands.[Method] We investigated the present situation of island vegetation resources such as Dayushan and Xiaoyushan Island by using the method of sampling and route,and analyzed seawater vegetation resources and the geographical composition.[Result] The majority part vegetation type were the formation of the original secondary or plantation while the original vegetation of the island occupied little percentage.The vegetation type accounted for very small proportion,while the shrub,grass and coastal vegetation type accounted for a large proportion of the natural vegetation.Plant species were abundant.The flora of the island had a wide and different degree of contact with the flora of flora around the world,and the geographical composition had certain diversity.[Conclusion] The results provide theoretical basis for the protection and development of islands vegetation resources.
