摘　　要：选用南京地区近5年来的地下水水资源量和地下水埋深,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和变化原因。结果表明:南京地区地下水可开采潜力较大,南京市有63.2%的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。提出了监测方式改革、监测站网调整等建议。Underground water resources quantity and the buried depth of monthly groundwater from 2010 to 2014 in Nanjing were selected.Undergroundwater exploitation potential was analyzed by mineable coefficient method,and dynamic change characteristics and reason of the changing were studied. The result showed that undergroundwater exploitation was comparatively potential in Nanjing,so that the mining of it could be appropriate to encourage. The water level of 63.2% deep undergroundwater decreased gradually with time from 2010 to 2013,and some area′s water level increased in 2014.The reform way of monitoring and monitoring network adjustment were put forward,to provide reference for deep undergroundwater resources management in Nanjing.
