| 摘 要： | 以石羊河流域下游民勤绿洲区域地下水为研究对象,运用地下水位动态ANN-FEFLOW模型模拟了不同情景下(现状条件、灌溉面积减少、节水灌溉实施、地表来水增加及综合工程措施等)地下水动态变化。结果表明,民勤绿洲现状条件下地下水将持续下降;灌溉面积减少可以明显缓解地下水位下降速度,节水灌溉对地下水的影响并不明显。地表来水为2.51×108 m3/a时,湖区地下水将出现正均衡;综合工程措施情景下,湖区和泉坝区地表来水分别为1.45×108 m3/a和2.51×108 m3/a时,地下水位回升。 |

| Abstract: | Groundwater dynamics in the Minqin oasis under several scenarios including current condition,the decrease of irrigation area,water saving irrigation,the increase of surface water and compositive measures were simulated using the ANN-FEFLOW model.The results showed that groundwater levels in the Minqin oasis would continue to drop in the current condition.Decrease of irrigation area could slow the drop rate of groundwater while the effect of water saving irrigation on groundwater was not obvious.Groundwater in the Huqu area would be plus equilibrium when surface water amount was 2.51×108 m3/a.Groundwater levels in the Huqu area and the Huanba area would increase under compositive measures with surface water amounts of 1.45×108 m3/a and 2.51×108 m3/a respectively. |
