湖北远安县苦槠天然林群落结构特征

Community Structure Characteristics of Natural Forests Castanopsis sclerophylla of Yuan'an County

在对湖北省远安县苦槠天然林群落调查的基础上,分析了该地群落物种组成、物种多样性等群落结构特征,拟为森林培育、造林树种选择及天然林资源保护等提供科学依据。结果表明:苦槠天然林群落物种多样性丰富,苦槠处于主要竞争地位,树种优势明显;乔、灌、草(藤)层次分明,现有苦槠群落处于针阔混交林向常绿阔叶与落叶混交林过渡阶段,并有向优势种继续发展的趋势;群落稳定性较强,更新良好,处于旺盛生长阶段。

Based on the investigation of the natural forest Province, the species composition, community structures and community of Castanopsis sclerophylla in Yuan＇an County of Hubei other structure characteristics were analyzed to provide scientific basis for forest cultivation,selection of afforestation species and the protection of natural forest resources. The results showed that there were abundant species diversity in C. sclerophylla community, which is in the main competitive position with obvious species advantages;The layers of arbors, shrubs and herbages （liane） could be distinguished clearly, there are C. sclerophylla communities in the transitional phase from the theropencedrymion to the evergreen broad-leaf forest,mixed deciduous forest, and there is a tendency to continue to develop towards dominant species; The stability of the C. sclerophylla community is strong with good update,and it is in the vigorous growth stage.
