摘　　要：选用南京地区近5年来的地下水水资源量和月地下水埋深,通过开采系数法分析南京地区地下水可开采潜力,研究地下水埋深动态变化趋势并分析变化原因。研究结果表明:(1)南京地区地下水可开采潜力较大,在不大幅度影响开采潜力的前提下可以适当放宽区域总开采量;(2)南京市63.2%深层地下水监测井代表区域地下水位随时间呈逐渐下降趋势,部分区域水位2014年有所回升;(3)提出了监测方式改革、监测站网调整等建议,为南京地区深层地下水资源优化管理提供参考。Underground water resources quantity and the buried depth of monthly groundwater from 2010 to 2014 in Nanjing was selected. Groundwater exploitation potential was analized by mineable coefficient method, and dynamic change characteristics and reason of water level of groundwater was analized. The Groundwater exploitation was more potential in Nanjing so that the min-ing of groundwater could be appropriate to encourage. The water level of 63. 2% deep groundwater decreased gradually with time from 2010 to 2013. The reform of the way of monitoring and monitoring network adjustment and so on was put forward, to provide reference for deep groundwater resources management in Nanjing.
