摘    要:随着工业规模的发展,各城市都面临着地下水资源如何科学利用的难题,北方缺水城市沈阳李官堡水源地就面临着新增工业造成的用水压力,如何对该水源地的水资源进行科学评价是合理取用水的前提。在对模拟区范围、边界条件和孔隙水介质进行概化和对水文地质参数及其他参数确定的基础上,将该区域地下水流系统概化为均质、各向同性、二维、潜水非稳定地下水流系统,运用GMS模型软件对研究区的地下水流场进行了数值模拟预测。通过模型识别和可靠性分析认为,所率定的模型参数符合实际且模型边界条件合理;预测认为该区域地下水资源量不能满足新增企业用水量9.8万m3/d的需求。该评价方法不仅具有应用和推广价值,而且具有为地下水资源科学规划提供科学依据的重要作用。

Abstract:With the industrial developing of Shenyang city which locates in the northeast of China,the groundwater resource demand is increasing and how to use the limited groundwater resource reasonably is a big problem.In this paper,the study area and the boundaries and the pore water medium are conceptualized and the hydrogeological parameters and other parameters such as source sink term and seepage recharge of stream and precipitation and etc have been identified.The groundwater aquifer is homogeneous and isotropy and the flow system in it is 2-D phreatic,and the GMS model software is used to simulate and predict the groundwater flow.By model identification and the reliability analyzing,the calibrated parameters and the identified boundaries are reasonable.And the predicted water resource quantities of groundwater resource can't meet the demand of water abstraction(98,000m3/d)by the new planning industries.The groundwater abstraction of the planning industries should be reduced or other water sources should be found.
Keywords:liguangpu water source  groundwater flow field  numerical simulation  predicting  GMS
