摘　　要：根据《陕西省地下水超采区划定与保护方案》,2015年划定靖边一般超采区,面积207 km^(2),年均超采量为237万m^(3),涉及东坑镇、宁条梁镇、新桥农场。本文通过2010-2021年长系列地下水位埋深、降水资料、主要农作物播种面积等基础资料,对研究区域地下水位年际及年内动态变化展开分析。结果表明:研究区域地下水位动态变化类型主要为开采型,降水及地表水对地下水的补给有限,为推进地下水超采区治理迫切需要“开源节流”。According to the Division and Protection Program of Groundwater Over-exploitation in Shaanxi Province,the Jingbian general over-exploitation area was delineated in 2015,with an area of 207 km^(2)and an average annual over-exploitation of 2.37 million m^(3),involving Dongkeng Town,Ningtiaoliang Town and Xinqiao Farm.Based on the long series of basic data such as groundwater depth,precipitation data and main crop planting area from 2010 to 2021,this paper analyzes the annual and annual dynamic changes of groundwater level in the study area.The results show that the dynamic change type of groundwater level in the study area is mainly mining type,and the precipitation and surface water supply to groundwater are limited.In order to promote the management of groundwater over-exploitation area,it is urgent to open source and save water.
