我国岩溶面积占国土面积的35.93%,其绝大部分分布在南方地区。植被的自然演替是岩溶地区生态重建的主要方式。土壤是岩溶地区不易再生的最稀缺资源。文章分析了自然演替过程中的环境特征、养分特征、土壤种子库等的变化规律。分析了岩溶地区植被的顶极群落以及群落演替方向的特殊性。
Karst area in our country accounts for 35.93% of the territory, most of which distribute in the southern China. The natural vegetation succession is a major means of ecological rehabilitation in Karst area. Soil is the most scarce and non - regenerated resource in Karst area.
