| 摘 要： | 大金山岛是上海海域存留天然植被较完整的海岛,对其现状进行调查和分析有助于制定具有针对性的海岛植被保护策略。文章基于21个样地的调查,将大金山岛植被划分为常绿阔叶林、常绿落叶阔叶混交林、落叶阔叶林、落叶灌丛和草丛5个植被类型14个群落类型。地带性森林群落径级结构和物种多样性特征分析表明,大金山岛森林群落结构相对稳定、物种多样性较高。为进一步完善大金山岛的植被保护措施,需加强植被分类与制图、量化典型植物种群大小和分布特征、跟踪管理大径材树木生长和健康状况、开展植被和动物综合调查以及植被动态长期监测的研究和管理。

| Abstract: | Dajinshan island is a relatively intact area protected to natural vegetation in Shanghai surrounding sea area.Investigation on current situation of vegetation will be helpful to formulate island plant targeted protection strategies.Based on 21 surveyed plots,the vegetation in Dajinshan island was classified to 5 vegetation types,including evergreen broadleaved forest,evergreen and deciduous mixed broadleaved forest,deciduous broadleaved forest,deciduous shrubs and grassland,as well as 14 community types.The results of size class distribution and species diversity indicated that community structure was relative stable and species were abundant across the zone forest communities.In order to improve the protect strategy of vegetation in Dajinshan island,the next necessary step is to strengthen research and management by focusing on vegetation classification and mapping,quantification of population size and distribution of typical plant species,tracking management of growth and health for large size trees,synthetical investigation between vegetation and zoo,and long-term monitoring vegetation dynamics. |
