摘要
本文在对宁夏石嘴山市的水文地质和地下水资源进行系统分析的基础上,建立了石嘴山市地下水水流模型。并采用有限差分法,利用P rocess ing M od flow软件对该市浅层地下水进行了数值模拟。在模型的拟合阶段和检验阶段,水头计算值与观测值的误差绝对值的平均值分别为0.28和0.18米,所有结果显示两者基本一致,说明所建模型符合实际,可以用于研究区地下水位与水量的近期及远景预测。
On the basis of systematic analysis on hydrogeology and groundwater resources in Shizuishan city of Ningxia Municipality, the article establishes groundwater flowing model and adopts limited differences method and makes use of the software of Processing Modflow to carry on numerical simulation of shallow groundwater in this area. In the fit and test phases of model, the average of absolute value of errors between calculation value and observation value of water head is 0. 28m and 0. 18m respectively. All results show that the both basically consistent and the model is accord with the practice, and can be used for forecasting groundwater level and quantity for short term and prospect in this area.
