植被的自然演替是岩溶地区生态重建的主要方式。
The process of natural succession of vegetation in Karst rocky desertification area in central Guizhou was divided into the herbosa stage,the stage of herbosa-shrub,the stage of vine-shrub,the stage of subaltern tree forest and the stage of evergreen broad-leaved forest according to the characteristic of plant community.
根据植物群落的特征,将黔中喀斯特地区石漠化后植被自然演替过程分成草丛阶段、草灌阶段、藤刺灌丛阶段、次生乔林阶段和常绿阔叶林阶段,应用物种丰富度指数、Simpson指数、Shannon-Wiener指数和Pielou均匀度指数分别研究各演替阶段草本层、灌木层、乔木层和群落总体的物种多样性。
