| 摘 要： | 采用空间序列代替时间序列的方法，研究喀斯特石漠化区植被演替过程中土壤质量变化特征。以广西都安澄江小流域为例，选取4个植物演替阶段，即乔木、灌丛、灌草丛、草丛的典型样地，对该地区土壤理化性质进行分析，研究植被演替对土壤质量特征的影响。结果表明：在石漠化地区植被演替过程中，土壤含水量、pH值、有机质、氮、磷、钾等含量均有一定程度的下降。导致这一变化的主要原因是植被生长情况、土壤养分积累能力等。 |

| Abstract: | The characteristic of soil quality during the vegetation succession process about rocky desertification in Karst regions of Guangxi was studied by using the method of the spatial sequence instead of the time series.Taking Chengjiang small watershed in Du'an County of Guangxi was chosen as an example,four stages of the reversal succession process about rocky desertification were chosen,including the typical plots of the arbor,shrub,bushes and short grass.The chemical and biological characters of soil and fur... |
