中文摘要	运用构造控水分析、水化学同位素等方法，对宁南南北古脊梁岩溶裂隙水系统进行了深入的分析与讨论。该区储水空间以岩溶裂隙为主，岩溶水的空间分布明显受SN向大型断裂构造控制。岩溶地下水以大气降水起源为主，并表现为多元水混合而成。水质分布呈现南优北劣的分带特征，北部水一岩相互作用形式为溶滤一蒸发浓缩型，呈高矿化咸水，南部为溶滤一混合型，呈低矿化淡水。根据水动力场和水化学场特征，划分了3个相对独立的岩溶水子系统。
英文摘要	Karst fissure groundwater in southeastern Ningxia has been synthetically analyzed by applying the theories of tectonic-con-trolled groundwater and groundwater geochemistry as well as isotope techniques. The results show that karst is not well developed in the area, the groundwater storage space is mainly made up of karst fissures, and the distribution of karst groundwater is strictly con-trolled by the NS-trending faults. Karst groundwater in this region mainly originates from atmospheric precipitation and is mixed with various sorts of primitive water. Groundwater quality shows zonal characteristics, i. e. , good in the south and bad in the north. The water-rock interaction is characterized by dissolution-evapotranspiration and produces salt water in the northern area. In the southern area the water-rock interaction has features of dissolution-mixture and produces fresh water. According to characteristics of hydro-dy-namic conditions and water chemistry, the whole karst system has been divided into three subordinate karst groundwater systems. The results have an important scientific significance in the study of the difference between the karst groundwater in western China and that in eastern China.
