摘要
以贵州省贞丰县兴北镇板围村现存的喀斯特植物群落为对象，分析了其群落的结构和组成、优势种群的生态位宽度及其分布格局、群落所处的小生境状况以及封山育林后群落的演替及动态，结果表明，该地区喀斯特小生境严酷，土壤分布零星且浅薄而石漠化比例大，现存植物种群则主要以集群分布和无性繁殖策略来适应这种小生境，因此为避免其进一步遭受破坏和继续退化，采取封山育林的方式是该地区恢复森林植被的重要途径之一。
Analysis were made on structure and composition, niche width and distribution of dominant population, habitat, succession and its dynamics after conservation for regeneration of the existing karst phytobiocenose in Banwei village, Xingbei town, Zhenfeng county, Guizhou province. The result demonstrated that the habitat has been disturbed with few and thin soil layer, and with rock-face large area. Therefore, the plant population has adapted to the habitat by colony and clonal regeneration. Conservation for regeneration is an important way to be recovered in the area.
