对黑石顶自然保护区森林次生演替过程中的群落结构、物种组成及物种多样性变化的研究结果表明：在皆伐裸地恢复阶段最初的２～４ 年，先锋种、阳生性种及中生性种的幼苗同时大量出现于次生裸地上；演替至１０ 年时，群落中先锋种的数量占绝对优势，阳生性种保持稳定，中生性种趋于减少；针阔叶混交林阶段，先锋种趋于减少，阳生性种趋于增加；阳生性常绿阔叶林阶段，先锋种基本衰退，而阳生性种占绝对优势，同时中生性种趋于增加；演替至中生性常绿阔叶林阶段，阳生性种逐渐消退，中生性种的数量占优势。皆伐裸地恢复阶段为群落垂直结构的形成期，仅有Ⅲ级以下立木，乔木层无明显分层，群落的个体密度无明显变化；由恢复阶段进入针阔叶混交林初期为群落垂直结构分化期，群落中出现大量Ⅲ、Ⅳ级立木，乔木层可分为３ 个亚层，但群落的个体密度因自疏作用而显著下降；针阔叶混交林阶段为群落垂直结构的相对稳定期，Ⅴ级立木多度和胸高断面积呈演替系列的第一个高峰，同时群落的个体密度显著增大；阳生性常绿阔叶林阶段为群落垂直结构的变动期，群落中Ⅴ级立木多度和胸高断面积大幅度下降，个体密度无明显变化；中生性常绿阔叶林阶段为群落垂直结构的稳定期，群落中各立木级趋于更加完善，胸高断面积达到演
The results of the study on the changes of community structure, species composition and species diversity in secondary succession process of forest in Heishiding Nature Reserve showed that in the first 2 ~ 4 years of restoration stage of bare land, the pioneer species, In the succession to 10 years, the number of the pioneer species in the community accounted for absolute advantage, the sun-born species remained stable, and the sexes tended to decrease; coniferous and broad-leaved mixed forest stage , The number of pioneer species tended to decrease, and that of yangsheng tended to increase. In the period of positive eucommia broad-leaved forest, the avant-garde species basically declined, while the yangsheng species accounted for absolute superiority while the number of middle-derived species tended to increase. In the stage of green broad-leaved forest, the number of male-derived species gradually subsided while the number of middle-type species dominated. There was no stratification in the arbor layer and no significant change in the individual density of the tree species in the bare-cut restoration stage of the clear cutting stage. The vertical structure of the coniferous and broad-leaved mixed forest from the recovery stage was the initial stage of community structure During the differentiation period, a large number of stand III and IV stands appeared in the community, and the tree layer could be divided into three sub-layers. However, the individual density of the community decreased significantly due to the effect of self-sparseness. The coniferous and broad-leaved mixed forest was the stable phase of the vertical structure , ⅤLevel height and thoracic area is the first peak of succession series, meanwhile, the individual density of the community increased significantly; The period of positive-euphorbia evergreen broad-leaved forest was the change of vertical structure of the community, The area of height and chest height decreased significantly, and there was no obvious change in individual density. The stage of mesogenic evergreen broad-leaved forest was the stable period of the vertical structure of the community, and each standing tree level in the community tended to be more perfect,
