Karst aquifers are particularly susceptible to pollution and require special management that takes into account their unusual mix of hydrological processes. Case studies are discussed of dispersed source contamination of nitrates in tertiary
in the saturated and unsaturated zones. Control is much easier for point-source sources of pollution.

The bare karst is the more widespread karst type in southern China. It is frequented by many environmental problems, such as drought, flood, water pollution, and deforestation. Surface collapse with 768 cases and 29 165 collapse pits is the major
