摘　　要：土地石漠化已成为喀斯特地区一种突出的生态环境问题,是西南喀斯特地区实现全面可持续发展的主要障碍因素之一。在参考国内相关研究的基础上,根据喀斯特土地石漠化过程对土壤特性及土壤微生物的影响,土壤微生物群落生态特征对土地石漠化的响应,利用土壤微生物作为生态监测指标,基于"干扰-响应"框架初步建立了一套喀斯特土地石漠化风险评价指标。Rocky land desertification has become a prominent ecological environment problem and its one of the main obstacles to realize comprehensive sustainable development in Southwest karst area.On the basis of reference the domestic relevant research in the field,according to the process of Karst rocky desertification influence of soil characteristics and soil microbes,and soil microbial community ecological characteristics response of rocky desertification,using soil microbial as ecological monitoring index,established a set of risk assessment evaluation indexes of karst rocky desertification;on the basis of interference-response preliminary framework.
