Description :
Northern and southern karst areas of China are all studied in this paper. On the basis of field observation, survey and chemical analysis, the difference of karst processes indicated by CaCO3 and pH values in fine and loose sedimentary strata as well as limestone strata , and the vertical cycle zone ascertained by predecessors can be divided into 3 subzones. Deep karst morphology near groundwater level under vertical cycle zone develops better in the middle and late periods of karst process.
