Rocky desertification induced by soil loss is a serious ecological problem in karst mountain areas. Lack of awareness in the local population of the need for soil conservation has led to intense human disturbance that has accelerated soil loss and in turn caused a high proportion of land in rural environments to undergo rocky desertification. In this review, we discuss five human-related causes that have accelerated soil loss in the rural karst mountainous areas of Guizhou Province, southwestern China. These causes include road erosion, house construction, steep slope cultivation, tourism development, and animal trampling. These activities destroy surface vegetation and increase the potential for soil loss through exposed swallow holes (karst fissures). In addition to the national development strategy of rural revitalization and countryside beautification already implemented in the western region, the human impacts on the rural environment must be addressed. We discuss some effective measures the government should adopt to control the various types of soil loss due to human activities. Our review and findings provide a better understanding of anthropogenic soil loss in karst rural environments and present information to raise people's awareness of measures that are needed to protect the soil resources in this region.
