| 摘 要： | 为研究外来入侵植物马缨丹的入侵机理,采用样地取样法,对海南岛不同生境中的马缨丹入侵群落的物种组成、植物生活型、物种多样性、丰富度、均匀度及群落相似性进行了调查分析,结果表明,群落中,植物种类约有75种,隶属31科66属,以菊科、禾本科、蝶形花科植物居多;植物的生活型主要有高位芽植物、地上芽植物、地面芽植物和一年生植物,而且干扰程度越低、高位芽植物所占的比例越大;物种多样性的取值范围在0.445 2～1.832 0之间,物种丰富度的取值范围为1.811 6～2.219 9,均匀度的取值范围为0.157 1 ～0.759 7;群落的相似性系数较低,均在0.5以下,最高的也只有0.347 8,表明群落的物种组成较分散,群落尚处于发育的初期阶段,还未形成稳定的群落.

| Abstract: | For the study of Mien invasive plant Lantana camara invasive mechanism, the quadrat sampling meth- od was used to investigate and analyze the plant composition, plant life form, plant diversity, richness, evenness and similarity of the community in different habitats in Hainan Island. The results showed that there are about 75 species, belonging to 31 families and 66 genera in the community. Most of the species are unde the families Compositae, Gramineae and Papilionaceae. Raunkaer＇ s life forms are mainly phaenerophytes, chamaephytes, hemicryptophytes and therophytes. Phaenerophytes had a higher proportion when the disturbance is lower. The range of the plant species diversity indices was 0.445 2 - 1. 832 0, the range of the plant species richness indi- ces was 1. 811 6 -2.219 9, and the range of evenness was 0. 157 1 -0.759 7. The community similarity coeffi- cient was lower than 0.5, the highest only being 0.347 8, indicating that the species composition of the commu- nity was decentralized relatively and that the community was still in the early stages of development and was sta- ble yet. |
