摘要/Abstract

摘要： 在野外调查的基础上,对姑婆山天然植被的种群组成和群落演替进行了研究。结果表明:在调查区共有植物92种,隶属于48科71属;用重要值指数分析各演替阶段中的优势种群可知各阶段的优势种没有显著的变化(草丛阶段除外),不少种类在2个或3个演替阶段中均为优势种,优势种的更替呈现一定的连续性,体现了群落演替主要表征为优势层及优势种的更替;对各演替阶段物种多样性进行测定,其多样性指数变化为常绿落叶混交林>常绿阔叶林>灌丛群落>草丛群落。在物种多样性预测演替顺序的基础上,利用演替指数法及演替度法,从群落物种多样性、植物种群优势度及相对频度等多方面来论证各阶段演替的顺序,证明各阶段演替顺序为:草丛阶段—灌丛阶段—常绿阔叶混交林阶段—常绿阔叶林阶段。

Abstract: This paper, based on the field research, presents an in-depth analysis on species composition and succession of natural vegetation in Gupo Mountains. The research suggests that there are in total 92 species of plants in this region, which belong to 48 genera and 71 families. What's more, with the important value index analysis of dominant population in each succession stage, it is concluded that there is no noticeable variation during each stage(except the stages of herbosa), and that quit a few species are dominant species during two or three succession stages. According to the determination of species diversity in each succession stage, the diversity index changes of these species are evergreen-deciduous mixed forest>evergreen broad-leaved forest>brush community>herbosa community. Besides, from the aspect of species community, the total dominance of plant species and relative frequency of each stage, this paper forecasts and demonstrates the order of succession in each stage based on species diversity by employing certain methods, which include index of succession and degrees of succession.The order of succession in each stage is grass,brush,evergreen-deciduous mixed forest and evergreen broad-leaved forest.

Key words: Gupo Mountains, natural vegetation, community composition succession
