摘要
在系统分析黑河流域中游平原区地质及水文地质条件的基础上,利用Visual MODFLOW和ArcGIS技术,建立了研究区地下水系统数值模型,利用研究区2012年1月1日至2012年12月31日地下水位动态观测资料对所建立的模型进行求解与识别,并利用识别后的模型对现状开采和调整开采条件下地下水位动态变化趋势进行预测。结果表明:现状开采条件下研究区地下水处于负均衡,地下水位持续下降;调整人工开采量大小及空间分布,地下水位变化趋势发生明显改变。该研究可为区域地下水资源合理开发利用提供依据。
On the basis of systematic analysis of the geological and hydrogeological conditions in the middle plains of Heihe River basin,this research establishes the numerical model of groundwater system by using Visual Modflow and ArcGIS,and uses the underground water level dynamic observation data of the study area from January 1,2012 to December 31,2012 to solve and identify the model. Then this research applies the identified model to forecast the dynamic change trend of the groundwater level under the current and adjusted exploitation conditions. The results show that the groundwater in the study area is in a negative balance under the current exploitation conditions, which means the underground water level continues to decline; adjusting the artificial exploitation in the quantity and the spatial distribution can significantly change the tendency of groundwater level. The research can provide ba- sis for rational development and utilization of regional groundwater resources.
