摘　　要：在海南东北部铜鼓岭热带滨海森林,选择同一坡向、同一海拔的自然森林样地,通过定位采样分析森林群落重要值较大的前20个树种的树干附生地衣(下称树干地衣)组成特点、水平分布特点及其与森林树木种类的关系。结果表明:该区森林树干地衣资源丰富,共收集到树干地衣26种,地衣内生真菌31种;同一个海拔高度,地衣群落组成并不集中,呈随机分布的状态;在树干离地面0~2.0 m的位置,树干地衣优先分布高度为0.6~1.4 m;其中,以海南大风子(Hydnocarpus hainanensis)为宿主的地衣最多,地衣对宿主的偏好与树种在群落中的地位无关,地衣的随机分布可能与宿主的随机分布有关。In the tropical coastal forest of Mountain Tongguling in the northeastern Hainan, quadrats with the same slope aspect and elevation in a permanent sampling site of the natural forest were selected to analyze the composition and horizontal distribution characteristics of arboreal lichens and their relationship with the forest tree species in the quadrats with first 20 tree species of higher important value in the forest community through positioning sampling. The results showed that the lichens resources were abundant on the trunks of the forest trees in this area. In the quadrats 26 species of arboreal lichens and 31 species of lichen-associated fungi were collected. At the same altitude, the composition of lichen community was scattered and distributed randomly. The preferential distribution height of arboreal lichens was 0.6-1.4 m on the trunk when the lichens were sampled from the trunk 0-2.0 m above the ground. Among all the hosts Daphnia hainanensis hosted most of the lichens. The preference of lichens was independent of the status of tree species in the community, and the random distribution of lichens may be related to the random distribution of hosts.
