摘　　要：地下水可开采量通常作为区域地下水合理开发利用阈值上限,是制定地下水治理和保护管控指标的首要依据。围绕把水资源作为最大的刚性约束,以水而定、量水而行,以维持山丘区地下水排泄结构稳定为目标,提出了以天然基径比为参照的山丘区地下水可开采量计算方法—基径比关系曲线法;以保证河道内生态环境需水量为目标,提出了以水资源开发利用程度为控制指标的山丘区地下水可开采量计算方法—地表水可利用量控制法。以赤峰市山丘区地下水可开采量计算为例,结果表明:赤峰市山丘区地下水可开采量为4.07亿m3,计算结果较为合理,计算结果与方法可推动赤峰市山丘区地下水实现合理开发利用与保护,维护区域生态安全,为我国北方山丘区地下水可开采量评价提供研究参考。The sustainable yield of groundwater is usually referred as the maximum threshold of groundwater exploitation and utilization at regional level,and it is an important control indicator for groundwater governance and protection.With the goal of maintaining the stability of the groundwater drainage structure in the hilly area,a method for calculating the recoverable amount of groundwater in the hilly area based on the natural base-diameter ratio—base-diameter ratio relationship curve method is proposed;to ensure the water demand of the ecological environment in the river course,A method for calculating the recoverable amount of groundwater in the hilly area,which takes the degree of water resources development and utilization as the control index,is proposed—the control method of the available surface water.It takes Chifeng City as an example,the sustainable yield of ground water in hilly areas is 407 million m3.The result matches the actual situation in Chifeng City therefore proving the calculation is rational.The yield in Chifeng City can promote the acceptable exploitation and sustainable use of groundwater,and maintain ecological security in that region.It can also be taken as a research reference for calculating sustainable yield of groundwater in hilly areas in China.
