Synopsis

Karst is a type of landscape which forms under a specific combination of geological conditions, precipitation, and temperature (Fleury 2009). It contains caves and extensive underground water systems that develop from especially soluble rocks such as limestone, marble, and gypsum (Ford and Williams 2007). Karst regions have always been characterized by environmental problems such as an impoverished ecosystem, soil degradation and erosion, deterioration of water quality and landform destruction (Urich 2002). Thus, a karst region can be considered among the most vulnerable land systems in the world.

The Karst mountainous region of Southwest China is one of the largest karst continuum belts in the world (Huang et al. 2008). Karst geomorphology is mainly concentrated in the Yunnan, Guizhou, and Guangxi provinces. There, the karst system experienced rocky desertification, a process of land degradation whereby an area formerly covered by vegetation and soil is transformed into a rocky...
