摘　　要：采用样线与样方相结合的调查方法,对南涧凤凰山州级自然保护区植物群落进行调查研究。结果表明,保护区内共有6个植被型、7个植被亚型、10个群系和18个群丛,植被类型多样。除尼泊尔桤木—紫茎泽兰群落乔木层和灌木层物种丰富度(S)最低外,相同群落灌木层S值明显高于乔木层。Sorenson相似性分析结果,两个群落物种间相似性灌木层高于乔木层。Shannon-Wiener指数(H)、Pielou指数(J)、Simpson指数(D)分析结果,半湿润常绿阔叶林和暖温性针叶林多样性较高,暖性落叶阔叶林多样性最低,同一群落灌木层D指数明显高于乔木林。群落乔木层和灌木层D、H、J指数与物种丰富度相关性不高;乔木层D指数与H指数、D指数与J指数表现为显著正相关;灌木层D指数与H指数、D指数与J指数、H指数与J指数表现为显著正相关。针对保护区植被类型、植物群落多样性等特征,提出加强对原生植被的保护、对外来入侵物种防控治理和开展生态修复等保护建议。The plant communities in Nanjian Fenghuangshan Nature Reserve were investigated by using the method of sample line and sample square.The results showed that there were 6 vegetation types,7 vegetation subtypes,10 formations and 18 associations in the reserve,and the vegetation types were diverse;except for the lowest species richness(S)in arbor layer and shrub layer of Alnus nepalensis and Eupatorium adenophorum community,the S value of shrub layer in the same community was significantly higher than that of arbor layer.Sorenson similarity analysis showed that the similarity between the two communities was higher in the shrub layer than in the tree layer.Shannon-Wiener index(H),Pielou index(J)and Simpson index(D)showed that semi-humid evergreen broad-leaved forest and warm temperate coniferous forest forest had the highest diversity,while warm deciduous broad-leaved forest had the lowest diversity,and the D index of shrub layer in the same community was obviously higher than that of arbor forest.The correlation between D、H、J indexes and species richness was not high in arbor layer and shrub layer;D index and H index,D index and J index of arbor layer showed significant positive correlation;D index and H index,D index and J index,H index and J index of shrub layer showed significant positive correlation.According to the characteristics of vegetation types and plant community diversity in the reserve,the protection suggestions such as strengthening the protection of native vegetation,prevention and control of alien invasive species,and ecological restoration were put forward.
