中文摘要	岩溶区生态恢复和重建是当今生态学研究的热点之一．研究自然更新过程中植物多样性变化对岩溶区退化生态系统的恢复和重建具有指导性意义．以桂林岩溶试验场为研究范围，选取具有代表性的垭口、1号洼地和砂页岩区3个样点（样方为20m*20m）进行种属组成、植物生活型谱和植物多样性研究．结果表明，丫吉村岩溶试验场经过近20年的自然恢复，其植物多样性增加，生境获得改善，整个区域的群落向着更加稳定的阶段演替．
英文摘要	In southwestern China, Karst area spreads widely and rocky desertification is very serious. How to resume and reconstruct ecology and harness rocky desertification is more and more concerned. In China, although numerous studies about the artifical rehabilitation at Karst area have been carried out, the effect on conservation and restoration of plant diversity has been found to be ineffective due to restricted selection and methods. Few studies have undertaken natural regeneration and plant diversity restoration. The present study was conducted in Guilin Karst experimental site of southwestern China to assess effects of natural recovery and conservation of plant diversity, so three samples （20 m * 20 m） were selected and investigated to analyze the special composition, life type and plant diversity. After 20 years of the ecological reconstruction, plant diversity increased quickly, the habitation was improved. This means that natural recovery is a very effective and rapid way to restore the destroyed forest and harness rocky desertification. Because of the complexity and dynamics of ecosystem, it is reasonable to adopt restoration according to various locations and objectives in stead of formula.
