摘要:

为合理利用灌区地表水和地下水资源，改善灌区生态环境，以人民胜利渠灌区为例，在对灌区地下水开发利用现状及其水位动态进行分析的基础上，将地下水模拟模型与GIS技术进行结合，并设置8个情景方案，预报了灌区5 a后地下水位变化趋势，并提出了灌区适宜的井渠用水比。结果表明，目前灌区地下水位呈不断下降趋势，削减灌区地下水开采量对地下水位的恢复有明显的作用。平水年削减10%的地下水开采量，人民胜利渠灌区井渠用水比例调整为1/0.78，上游调整为1/1.24，中游调整为1/0.85，下游调整为1/0.41，灌区机井数从原来的20 261眼削减到14 315眼，可以基本实现地下水的采补平衡。

Abstract:

In order to rationally use surface water and groundwater resources, improve the ecological environment of irrigation area and provide the basis for the realization of the most stringent water management, taking People's Victory Canal irrigation district as the research area, ArcGIS was used to analyze the People's Victory Canal irrigation district groundwater utilization status, and MODFLOW model was used to establish a fully irrigated three dimensional flow numerical simulation model. Eight different programs were set up to simulate the water level of the programs running in five years, and analyze the trends in groundwater level. The results showed that irrigation district ground water level showed a downward trend, reducing groundwater extraction played a significant role in the groundwater level recovery. In flat water year, reducing 10% of the groundwater exploitation, the well-canal irrigation proportion was 1/0.78, of which upstream was 1/1.24, midstream was 1/0.85, the downstream was 1/0.41, and the change well number from the original 20 261 eyes to 14 315 eyes could make the dynamic groundwater balance.
