Especially, the underground leakage is not well known by people. In this paper, we analyze the causes of rocky desertification from natural and human factors. Then,we give detailed analysis on the hazard and the active mechanism of the soil and water underground leakage in Karst rocky desertification. Finally,by summarizing the research methods of soil underground leakage,we propose the prevention and control measures of underground soil and water leakage in Karst rocky desertification. The purpose of thispaper is to provide basis and reference for the control of underground soil and water leakage in Karst rocky desertification.
