Types of soft soil in karst laterite and its engineering properties;

岩溶红土地基中的软土类型及其工程特性

Taking an example of karst soils from Guanling-Zhengfeng area, southwestern Guizhou, China, changes of soil total and available pool of major nutrients, microbial biomass carbon and soil respiration, activities of major soil enzymes in a degradation-reclamation sequence were studied.

因此，在分析岩溶土壤和生态系统退化过程的本质以及评价生态恢复的效应时，不仅应将微生物量碳和总养分库指标作为岩溶土壤退化恢复的指标，更应将微生物的质量和功能指标纳入关键评价内容。
