///The large examples of against drought and development of deep water wells to prove that karst groundwater resources show different in certain rules to follow South Guizhou karst region on water-rich sounding abnormal type and causes, single abnormal type sounding curve can be divided into the slow rise, slow down type, platform type low resistance, low resistance V-type, low resistance level rise type, low resistivity drop tail type, abnormal type of water-rich sections of apparent resistivity section sounding contour can be divided into low resistance U-type, low resistance O-type, low resistivity gradient banding, step-type low resistance.
