Analysis on Karst Groundwater in the Montainous area of Southern Pingliang

The Karst groundwater is analyzed by using the theories of tectonic controlled groundwater and groundwater geochemistry and isotope techniques as well as groundwater trends in southern Pingliang.The groundwater stored space is main karst fissures,and the distribution of karst groundwater is strictly controlled by the NNW trending faults.The Karst groundwater mainly originates from atmospheric precipitation.The water-rock interaction is characterized by dissolution-mixture and produces fresh water in the area.Groundwater trends take on climate model.According to characteristics of these,the whole karst groundwater has been divided into three comparatively absolute systems.
