安徽神山国家森林公园植物群落分布格局研究

Study on the Distribution Pattern of Plant Community Diversity in Shenshan National Forest Park of Anhui

为分析安徽神山国家森林公园植物群落分布特征,为其物种多样性保护提供参考依据,以群落调查数据为基础,分析比较不同植物群落的结构特征及乔灌草各层的物种多样性.结果表明,安徽神山森林公园调查样地可分为10个群落,其中乔木层以黄连木(Pistacia chinensis Bunge)、朴树(Celtis sinensis Pers.)、麻栎(Quercus acutissima Carruth.)、侧柏(Platycladus Spach)、马尾松(Pinus massoniana Lamb.)、湿地松(Pinus elliotti Engelm)为主要优势种,灌木层以小叶女贞(Ligustrum quihoui Carr.)、山胡椒〔Lindera glauca(Sieb.et Zucc.)Bl〕、柘刺〔Cu⁃drania cochinchinensis(Lour.)Kudo et Masam.〕、野桐(Mallotus Lour.)、悬钩子(Rubus corchorifolius L.f.)、卫矛〔Eu⁃onymus alatus(Thunb.)Sieb〕等为主要优势种,草本层以求米草(Oplismenus undulatifolius)、老鸦瓣〔Tulipa edulis(Miq.)Baker.〕、天葵(Semiaquilegia adoxoides Makino)等为主要优势种.各类群落的物种丰富度表现出草本层>乔木层>灌木层的特点;Simpson指数与Shannon-wiener指数表现为草本层>灌木层>乔木层的趋势;均匀度指数Pielou乔木层均匀度较低.

The species diversity of plant communities in Shenshan national forest park was analyzed,which could provide reference for plant diversity protection.Based on the standard sites in Shenshan national forest park,the authors analyzed the structural characteristics and the species diversity of different populations.the results showed that according to plant distribution status,growth environment and structure characteristics,investigation plots can be divided into 10 associations,vertical structure of this community can be divided in⁃to three layers of arbor,shrub and herb,in which the main dominant species in arbor layer are Pistacia chi⁃nensis Bunge,Celtis sinensis Pers.,Quercus acutissima Carruth,Platycladus Spach,Pinus massoniana Lamb.,Pinus elliotti Engelm,those in shrub layers are Ligustrum quihoui Carr.,Lindera glauca(Sieb.et Zucc.)Bl,Cudrania cochinchinensis(Lour.)Kudo et Masam,Mallotus Lour.,Rubus corchorifolius L.f.,Euonymus alatus(Thunb.)Sieb,and herb layers are Oplismenus undulatifolius,Tulipa edulis(Miq.)Baker.,Semiaquilegia adox⁃oides Makino.The abundance degree of community showed herb layer>tree layer>shrub layer,and the total ten⁃dency of diversity index Simpson and Shannon-wiener in the sample land showed the following order:herb layer>shrub layer>tree layer;uniformity Pielou showed lower uniformity law among every layers.
