| 摘 要： | 通过对黔中退化喀斯特森林结构分析表明,退化群落属于自然恢复的早期,从草本群落阶段到灌乔林过渡阶段,种组重要地位发生变化,先锋种组重要地位由大变小,顶级种组变化与先锋种组的相反,次先锋种组和过渡种组则先增大后降低;群落层次增加,主要层由灌木层发展到乔木层,高度逐渐增高,径级增大,个体数量从灌草阶段到灌木林阶段增加,之后减少;灌乔林过渡阶段群落乔木层物种多样性指数低,而灌木层多样性指数高。

| Abstract: | This paper discussed structure dynamic of community in the natural restoration process of degraded karst forest community in central Guizhou .The results showed that from herb stage to shrub-tree stage the pioneer species gradually reduced, climax species was just contrary from herb to shrub-tree stage , the sub-pioneer species and transition species increased firstly and decreased afterward. The layer and height as well as diameter of community was increaded. Individual number increased firstly and decreased afterward. In shrub-tree stage ,the species diversity in tree layer was lower than that of shrub layer . |
