Abstract: Investigation was carried out on vegetation resources in Jiedong Sangpu Shuanglu Nature Reserve by route survey and typical sample plots.There are 580 species of vascular plants,belonging to 129 families,371 genera.The tropical and sub-tropical taxa are predominant,taking up 75% of seed plant flora.The original vegetation is sub-tropical evergreen broad-leaved forest,composing by communities of Lithocarpus and Cyclobalanopsis,but its percentage of area is not great.The area of Pinus massoniana community and Acacia confuse community is large.It is concluded that the activities of human have great impact on the composition and structure of forests.Hill closing for reforestation and stand improvement are recommended,helping the succession from coniferous forests and coniferous and broad-leaved forests to region-specific climax communities.

Key words: Jiedong Sangpu Shuanglu Nature Reserve, flora, vegetation type

摘要： 通过线路调查结合典型样地调查,对广东揭东桑浦双麓自然保护区进行植被资源调查。据统计,保护区内共有维管植物580种(含种下等级),隶属129科371属。植物区系以热带、亚热带成分占明显优势,占种子植物科属的75%左右。原生植被为南亚热带常绿阔叶林,主要为石栎林和青冈林,但其覆盖面积比例较小,人工营造的马尾松林、台湾相思林等占有较大的比例。由此可见,人为经营活动对林分组成和结构的影响较大,宜采取封山育林、林分改造等营林措施,促使现有的针叶林和针阔混交林朝地带性顶级群落演替。
