摘要
赤皮青冈是现存壳斗科植物的原始类群,是受国家II级保护的珍贵树种。采用样方法,对湖南靖州赤皮青冈的种类组成、群落外貌、结构特征及物种多样性进行了研究。结果表明:在1 200 m2样地中,共有维管束植物67种,隶属于35科51属,其中优势科主要有豆科、蔷薇科、大戟科、冬青科、樟科、山茶科、禾本科、金缕梅科等;该群落是以赤皮青冈为主的单优种群落,群落季相明显;群落结构依次可划分为乔木层、灌木层、草本层;灌木层植物种类相对较丰富,对群落物种多样性具有较大影响,物种多样性的大小顺序依次为草本层>灌木层>乔木层。
The characteristics and species diversity of Cyclobalanopsis gilva community in Jingzhou, Hunan province were studied based on thecommunity investigations. The results show that 67 species in 51genera and 35 families of vascular plants were recorded in l 200 m2 plots, in which the dominant families were Leguminosae, Rosaceae, Euphorbiaceae,Aquifoliaceae, LauraceaeTheaceae, Gramineae and Hamamelidaceae; the community is the largest consociation that C. gilva predominated the forests, the aspection is obvious;the stratification of the forests was very obvious, which can be divided into arbor, shrub and herbaceous layer;the shrub layer was relatively abundant in species and had a greater effect on the community diversity, the diversity indexes for every forests ordered from high to low:herbaceous, shrub and arbor.
