| 摘 要： | 对苏丹中部的北杰济拉(Gezira)省地下水的水化学特征进行了评价，评价方法包括地下水主要离子浓度的监测分析及矿化度、钠离子、重碳酸根离子和氯离子浓度等值线图的绘制．对每个含水层的的水化学特征及其地下水的管理问题进行了深入讨论，并对地下水的适用性进行了详细分析．在含水层上部存在的化学成分含量较高及碳酸钙的存在，是蒸发作用和渗入量增加的结果．

| Abstract: | This paper presents an assessment of the hydrochemical characteristics of groundwater in Northern Gezira State, Central Sudan. The approaches followed here include the chemical analyses for major ions chemistry and construction of hydrochemical maps of total dissolved solids (TDS), sodium (Na +), bicarbonate (HCO 3 -), and chloride (Cl -) ions. The hydrochemical characteristics of the groundwater in each aquifer and management consideration are discussed. Sources of major ions in groundwater are analyzed. The hydrochemical maps of important species are constructed. The relationship of groundwater to use is elaborated. High concentrations of the chemical and hydrochemical constituents and the occurrence of calcretes (CaCO 3) in upper zones suggest a long history of evaporation and increasing leachates. |
