目的:明确天平山淫羊藿在重庆的分布区及其群落特征,为资源的可持续利用提供依据。方法:通过实地调查,并用GPS定位,在此基础上采用样方法,对不同生境中天平山淫羊藿分布相对集中的7个样地所有物种的多度、频度和重要值进行统计和分析。结果:天平山淫羊藿分布于重庆市长寿区、垫江县、忠县及丰都县,分布区海拔351~663 m,群落类型包括针叶林、阔叶林和竹林。群落植物有33科48属56种,优势种主要是乔木层的料慈竹、栎类、柏木等,灌木层的海金子、檵木、铁仔等,草本层的蝴蝶花、五节芒、长穗腹水草、披针薹草、天平山淫羊藿等。7个植物群落的物种丰富度指数D在1.1143~3.7781之间,群落中物种种数相对较少,个体数量相对较多;群落3和群落6的物种多样性指数H’和均匀度指数E都相对较低,群落物种分布具有明显的不均匀性。乔木层的D值、H’值和E值均低于灌木层和草本层,物种多样性较其余两层差。结论:建议将天平山淫羊藿收载入中国药典,作为正品淫羊藿药材之一。
OBJECTIVE: To determine the distribution and community characteristics of epimedium in Tianping Mountain in Chongqing, and to provide the basis for the sustainable utilization of resources. Methods: Based on the field survey and GPS positioning, the sampling method was used to analyze and analyze the abundance, frequency and importance of all species in 7 plots with different concentrations of Epimedium kadsura in different habitats . Results: Epimedium elegans distributed in Changshou, Dianjiang, Zhongxian and Fengdu counties in Chongqing. The distribution area is 351 ~ 663 m above sea level. The community types include coniferous forest, broadleaf forest and bamboo forest. There are 33 families, 48 genera and 56 species in the community. The predominant species are the species of Phyllostachys chinensis, oaks and cypress trees in shrub layer, sea gold, alder, Asus long grass, lanceolate grass needle, Epimedium, such as Mount balance. The species richness index D of the seven plant communities ranged from 1.1143 to 3.7781, with relatively few plant species in the community and relatively large numbers of individuals. Species diversity index H ’and evenness index E in both community 3 and community 6 Relatively low, the community species distribution has obvious inhomogeneity. The D value, H ’value and E value of arbor layer were lower than shrub layer and herb layer, and the species diversity was worse than the other two layers. Conclusion: It is recommended that Epimedium yunnanensis collected in the Chinese Pharmacopoeia, as one of the authentic Epimedium medicine.
