摘　　要：地下水是志丹靖边地区主要的用水来源,针对该地区水资源短缺的问题,通过控制性数值试验的方法,选择志丹靖边地区典型的区域,分别设计不同的方案,建立数值模型,对地下水的不同开采方式和开采强度下的降落漏斗形态和最大水位降深进行计算。结果表明,通过线状布井的方式沿河谷布设开采井优于在研究区内平均布井,并且线状开采强度应控制在600~800m3/d·km-1。对志靖地区地下水的合理开采具有指导意义。Groundwater is main water source of Zhidan and Jingbian regions in China.Aiming at resolving its water shortage,this paper used the controlled numerical test,chosen its typical area,designed different schemes to calculate the shape of the falling funnel and maximum drawdown under different means and intensity of groundwater exploitation.The results show that it is superior to build wells by linear well pattern along the valley than that by the average well pattern in the study area.The linear mining intensity should be controlled within 600~800 m3/d·km-1.This paper could have guiding significance for the rational exploitation of groundwater in Zhijing area.
