| 摘 要： | 应用Shannon-wiener多样性指数、Pielou均匀度指数、Margalef丰富度指数对林区的典型林分(锐齿栎林、油松林、华山松林)群落结构和多样性进行了分析,结果表明:乔木层、灌木层、草本层多样性均表现为:华山松林>油松林>锐齿栎林;从不同群落类型方面来看,由茜草+凤毛菊-苦糖果+悬钩子-油松+梾木组成的油松林群落丰富度最大,处于演替的进展阶段,由蕨类+禾本科-菝葜+忍冬-锐齿栎组成的锐齿栎林群落丰富度最小,群落的演替有逆行进展的趋势。

| Abstract: | Community structures and diversities of the typical stands(such as Quercus aliena var.acuteserrata,Pinus tabulaeformis,P.armandii) of Huoditang forest farm,Qinling Mountains were analyzed by indices of Shannon-Wiener diversity,Pielou evenness,and Margalef richness.The results showed that diversities of the trees,shrubs,herbers in different forest stands were in the order of P.armandii>P.tabulaeformis>Q.aliena var.acuteserrata.From the perspectives of different community types,the highest community richness appeared in the P.tabulaeformis community composed of Rubia cordifolia+Prunus mume-Malus baccata+Rubus corchorifolius-P.tabulaeformis+Cornus florida,which was in the developing succession stage,while the lowest community richness appeared in the Q.aliena var.acuteserrata community,composed of Pteridophyta+Poaceae-Smilax china+Lonicera sempervirens-Q.aliena var.acuteserrata,which was in the reverse succession stage. |
