摘要
应用MODFLOW软件,模拟分析了解放闸灌域地下水动态的变化特征,模拟结果表明河套灌区引黄水量减小到40亿m3后,在现有耗水结构条件下,解放闸灌域地下水位6年后的降幅为0.5 m左右,而12年后降幅为1m左右,且下降主要发生在中部和东北部地区,南部相对较小。为解放闸灌域治理土壤盐碱化,合理利用地下水资源提供重要的参考依据。
Based the software of MODFLOW, we modeled the groundwater dynamics. Results indicated that with the diverted water from Yellow river decreased to amount of 40×10^8 ma , the groundwater table will decrease by 0.5 m for 6 years and 1 m for 12 years later under the current structure of water consumption. It cound have useful suggestions for solutions of the soil secondary salinization and reasonable utilization of the groundwater resources in Jiefangzha irrigation scheme.
