摘要:
通过分析石漠化演替进程中土壤质量的变化特征，探讨土壤质量变化与石漠化之间的关系.结果表明：在石漠化的演替进程中，土壤有机质、氮、磷、钾、微生物量和腐殖质品质均有不同程度的下降，土壤质量的变化与石漠化的发展阶段具有方向一致性和阶段同步性的特点.运用聚类分析方法对岩溶石漠化进程中各演替阶段的土壤质量指标进行了较为全面的分析，并从中筛选出石漠化进程土壤质量退化的预警性指标.
Abstract:
According to the analysis of the variation of pH, the contents and the composition of organic matter,major nutrient elements(N, P,K) and the microbial biomass of the soils,it is found that the soil quality degenerated quickly with the development of karst rocky desertification.The method of hierarchical cluster analysis was used to evaluate the early warning indicators of soil quality degeneration in the process of karst rocky desertification.
