| 摘 要： | 内蒙古河套灌区节水改造后,引黄水量大幅度减少。在河套灌区内选择一块有代表性的区域作为研究对象,探讨河套灌区全面实施节水改造方案后,地下水开发利用的可行性以及井渠结合的合理模式。以MODFLOW软件为计算工具,对不同水井布局方案在某一确定的地下水开采强度下计算区地下水动态变化过程进行预测。计算结果表明,井渠结合区每年开采1200 m3/hm2条件下,连续多年运用能够保持采补平衡。不同的水井布局方案的计算表明,1200 m3/hm2开采水平下,以局部集中布井的布局形式较好。

| Abstract: | Allowed intake for irrigation use from the Yellow River would be cut down sharply when the water-saving reform project accomplished in Hetao irrigation district in Inner Mongolia.The feasibility of groundwater utilization,and the efficiency and appropriate pattern in conjunction use with groundwater and surface water(Yellow River) under water-saving irrigation conditions were studied.MODFLOW was used as a tool for evaluating groundwater resource and simulating groundwater dynamic procedure.Several different well exploitation rates and wells layout patterns were simulated in selected area.The results showed that 1200 m3/(hm2·a) exploitation rates can keep groundwater table balance and the partial centered layout pattern is better than our choices. |
