| 摘 要： | 采用时空替代法研究广西阳朔岩溶植被在演替过程中的种群变化和物种多样性。研究表明,随着演替的进展,耐荫种群增加,乔木种群增加,优势种的更替呈现出一定的连续性,后一演替阶段的优势种往往已经隐含在前一演替阶段中;物种丰富度随演替进展表现出草丛<落叶阔叶林<灌丛<常绿落叶阔叶混交林的趋势;灌木层的物种丰富度在各演替阶段中均是最高的;在各演替阶段中,落叶阔叶林阶段的群落均匀度均表现为最大。

| Abstract: | The characteristics of population variation and species diversity in succession processes of Karst vegetation in Yangshuo in Guangxi have been studied by a spatial series representing temporal series.The results showed that,with the development of succession,shade-tolerant populations and tree populations increasedt,he replacement of dominant species took on certain continuity,the dominant species of the process have hided in the former community;in the process of succession the species richness revealed the tendency of herbosa
