摘　　要：研究区地处赣、抚河流冲积平原区,潜水为研究区开采主要含水层,潜水径流主要受地貌形态的控制。潜水含水层的补给主要是河流侧向补给、大气降水的入渗及第三系红层越流补给,丰水期赣江、抚河水补给地下水为主,枯水期以地下水往河流排泄为主;平水期,地表水与地下水交替补排。赣抚流域为典型的硅酸盐地区,地下水水化学受硅酸盐、碳酸盐及人类活动影响,研究区粘土层较厚,湖水对地下水影响不大。人工开采是地下水的主要排泄途径,近年来地下水水井不断减少,但以南钢为中心的降落漏斗最大可达10 m,影响范围较大。The study area is located at the alluvial plain area of Ganjiang River and Fuhe River. The phreatic water is the main aquifer for the study area,and the phreatic runoff is mainly controlled by the topography. The recharge of phreatic aquifer is mainly the lateral recharge of the river,infiltration of atmospheric precipitation and the recharge of tertiary system sandstone. During the flood period,Ganjiang River and Fuhe River recharge groundwater,and the groundwater discharges into the two rivers during the dry season. And the surface water and groundwater recharge and discharge alternately in their normal level. Ganjiang and Fuhe basin is a typical silicate area,and groundwater chemistry is affected by silicate,carbonate and human activities. The clay layer in the study area is thicker,and the lake water has little influence on groundwater. Artificial groundwater exploitation is the major excretion pathway,and in recent years the groundwater wells continue to decrease. The cone of depressions centering around Nangang Factory is up to 10 m,which influences a large sphere.
