乌鲁木齐河流域柴窝堡盆地与河谷区是乌鲁木齐市的重要供水水源地。为了更好地为地下水资源的可持续开发提供依据,本文尝试将几何形状及含水层厚度差异悬殊的柴窝堡盆地与河谷区联合起来,运用GMS模型系统建立了区域地下水稳定流和非稳定流数值模型。通过对观测孔地下水位过程线和地下水流场进行拟合,校正了研究区的渗透系数、给水度和储水率等水文地质参数。并运用模型分析了研究区的地下水流系统、地下水均衡量、地下水位变化趋势及地下水位监测网的设计。结果表明研究区地下水流主要存在两个径流排泄区:沿乌鲁木齐主河道的径流排泄区和以柴窝堡湖和大小盐湖为排泄中心的径流区;地下水储存量相对较大,能够调节季节性变化与地下水开采的影响;应加强主要河流洪积扇补给区和山前侧向补给带地下水位的监测与排泄区泉水流量的观测。
The Urumqi River Basin The Chaiwopu Basin and the River Valley are important water supply sources in Urumqi. In order to provide the basis for the sustainable development of groundwater resources, this paper tries to combine the Chaiwopu Basin and the valley with different geometric shapes and aquifers thickness. The GMS model system is used to establish regional groundwater steady flow and unsteady flow Numerical model. By fitting the process line of groundwater level and the groundwater flow field in observation hole, the hydrogeological parameters such as permeability coefficient, water supply and water storage rate in the study area were corrected. The model was used to analyze the groundwater flow system, the groundwater balance, the trend of groundwater level and the design of groundwater level monitoring network in the study area. The results show that there are mainly two runoff and drainage areas in the groundwater flow in the study area: the runoff and discharge area along the main channel of Urumqi and the runoff area with the Chaiwopu Lake and the size salt lake as excretory centers; groundwater storage capacity is relatively large and can adjust seasonal changes And the exploitation of groundwater; the monitoring of spring water level in the monitoring and drainage areas of the floodplain recharge area and the mountainside recharge area should be strengthened.
