摘　　要：喀斯特地区生境严酷、地貌复杂、退化现象普遍,其植被恢复和重建已受到越来越多的关注;调查了石林地区不同恢复群落中团花新木姜子种群的分布格局、繁殖方式、径级结构等特征,结果发现:群落演替由最初到顶级,团花新木姜子呈由均匀到集群再到均匀的分布特征;团花新木姜子兼具有性和无性两种繁殖方式,恢复前期以无性更新为主,后期有性更新占优势;在恢复过程中,该物种先以数量优势占据生境,后期由于竞争保留少数大径级植株,其产生的大量实生幼苗只有少数在竞争中存活下来。It has hard habitats, complicated landforms and extensive degraded phenomena in Karst area, more and more people pay attention to the vegetation restoration and rebuilding. This article investigates the characteristic of distribution pattern, regeneration and size-class structure of Neolitsea homi lantha in different communities＇ restoration in Shilin. The research shows： from the former to the later, Neolitsea homi lantha has the characteristics from homogeneous distribution to clump, to homogeneous distribution in the end. Neolitsea homi lantha both have asexual propagation and generative propagation. Asexual regeneration dominants former stage and after that generative regeneration takes place of it. In the process of restoration, the species dominants in the habitats for their quantity superiority first, later they reserve large size-class plants because of competition, but then only a few seedling plants they birth survive in the competition.
