摘要

采用空间代替时间法研究了扰动边坡植被恢复过程中的土壤性质演变。结果表明，扰动边坡植被恢复过程中土壤含水量呈上升趋势，土壤容重呈下降趋势。随着植被的恢复，土壤物理性质逐渐改良。土壤有机质、全氮、速效氮、微生物量碳、微生物量氮、土壤呼吸呈上升趋势。全磷和全钾变化趋于稳定，速效磷和速效钾随着植被恢复演替在前期呈现增加的趋势，随后又降低，最后趋于稳定。土壤微生物呼吸速率随着植被恢复年限的增加呈上升趋势，说明植被在恢复过程中，土壤的熟化程度越来越高。

Abstract

Bv taking disturbed slopes as research sites

soil quality characteristics during community succeslion on disturbed slopes were studied by the method0 space substitute for time.The main conclusions are as follows:During the process of vegetation restoration，soil moisture rose and soil bulk density declined

which indicate that soil physical properties were gradually improved.Soil organic matter

total nitrogen

available nitrogen

soil microbial biomass carbon
