【摘要】：针对目前西北内陆河流域地下水总量控制指标制定方法的不足,提出了一套完整的确定区域/流域地下水总量控制指标的技术方法,主要步骤包括:以生态保护/恢复为约束条件,转换为定量化的判据;使用数值模拟方法确定地下水可开采量;进行供需平衡分析,分阶段定量确定地下水总量控制指标。应用此方法在甘肃省石羊河流域下游的红崖山灌区进行了实例研究,评价得到研究区2020年中期规划地下水总量控制指标为10 833×10~4m~3,2030年远期规划的指标为10 700×10~4m~3,与已有的控制指标相比相对宽松,在技术方法上也具有合理性。
[Abstract]:A complete set of technical methods to determine the control index of the total amount of groundwater in the region / basin is put forward in view of the shortage of the present method for establishing the index of the total amount control of groundwater in the northwest inland river basin. The main steps include: taking ecological protection / recovery as the constraint condition and converting to the quantitative criterion, and using the numerical simulation method to determine the open ground water. This method is applied to the hongyasan irrigation area in the lower reaches of the Shiyang River Basin of Gansu Province, and the index of the total amount control index of the total amount of groundwater in the mid 2020 plan of the study area is 10833 x 10 ~4m~32030 years, which is 10700 x 10~4m. ~3 is relatively loose compared with the existing control indicators, and is also reasonable in terms of technology and methods.
