分析了黑石顶针阔叶混交林在10年演变过程中的群落结构变化.结果表明,群落垂直分层日益明显;群落水平结构指标,盖度、密度、胸高断面积均有较大幅度增加;群落物种组成结构总体上变幅不大,但针叶树马尾松、杉木的优势地位明显衰弱,阔叶树木荷、腺叶山矾、鸭脚木等种的优势地位显著增强,整个群落由针叶阔叶混交林朝着阔叶针叶混交林演变;群落乔木层物种多样性、均匀度在增加,生态优势度在降低,群落向着复杂化、多层化方向发展. The results showed that the vertical stratification of the community was more and more obvious, and the horizontal structure index, cover, density and area of ​​chest height all increased greatly. The community However, the predominant position of coniferous masson pine and Chinese fir obviously weakened. The dominance of broad-leaved tree species such as broadleaf trees, The results showed that species diversity, evenness, ecological dominance decreased, and the communities developed towards complex and multi-layered.
