摘　　要：研究大围山樱属植物群落结构特征和物种多样性,为野生樱属植物保护和利用提供科学依据。结果表明:大围山樱属植物有钟花樱桃群落、尾叶樱桃群落、华中樱桃群落和雪落樱桃群落,生活型结构以高位芽植物为主,植物区系组成以泛热带植物成分为主。物种多样性为灌木层>乔木层,尾叶樱桃群落>华中樱桃群落>钟花樱桃群落>雪落樱桃群落。种群以中幼龄和壮龄树个体为主,群落处于稳定期。雪落樱桃种群地径结构呈典型的金字塔结构,属增长型种群。华中樱桃群落是以华中樱桃为优势种的单优群落,尾叶樱桃和钟花樱桃是其群落乔木层重要伴生种,这3种樱桃均缺乏更新幼龄树,有被其他针阔叶树种取代的趋势。To provide a scientific basis for the conservation and exploitation of wild Cerasus species in Dawei Mountain,we investigated the community characteristics and species diversity of Cerasus species.The results showed that there were four Cerasus communities,C.campanulata,C.diel-siana,C.conradinae and C.xueluoensis,in Dawei Mountain.Phaenerophyte in the life form and pantropical elements in the local flora were both dominant.The shrub layer had higher species diversity than that of the arbor layer.Species diversity of those four communities was following the order of C.dielsiana,C.conradinae,C.campanulata and C.xueluoensis.The community structure was relatively stable when young and mature individuals of Cerasus predominated.The ground dia-meter class structure indicated that the C.xueluoensis population was a growing population with a typical pyramid structure.The C.conradinae community was mono-dominated by C.conradinae,with C.dielsiana and C.campanulata as the important companion species.Those three Cerasus species would be replaced by other coniferous and broadleaved species due to the shortage of natural regeneration.
