14.1Introduction
Rocky karstification in karst areas (also called karst rocky desertification (KRD)) is considered one of the major factors that contribute to the global carbon balance as a global CO2 sink (Xu and Jiang 1997; Jiang and Qin 2011; Zhou et al. 2015). With the increasing interest in global carbon emissions, studies and analyses through comparing historical data with current data may discover how rocky karstification contributes to long-term environmental changes over decadal spans.
Guangxi is located in the southwestern karst area in China, and the KRD area is approximately 23,790.80 km2, accounting for 19.8% of the total KRD area in China in 2005. ...
