根据陕西省吴堡县岔上水源地水文地质条件，确定了研究范围和边界条件，建立了研究区水文地质概念模型和地下水二维非稳定流数学模型，利用基于有限差分法的Visual M ODFLOW 进行地下水流数值模拟计算。经过模型的识别和验证，获取可靠的水文地质参数，然后对水源地地下水资源进行定量评价。通过对比设计了9种开采方案，选取了最为合理的开采方案，最终得到岔上水源地平枯期允许开采量均为6880 m3/d。根据模型预报结果，水源地目前的设计开采量是可行的。研究结果为研究区地下水资源的合理开发利用提供了依据。

Based on the hydrogeological conditions of Chashang water source area in Wubao County of Shaanxi Province, the study area and boundary conditions were determined, and the hydrogeological concept ual model and two-dimensional unst eady mathematical groundwater flowwere constructed. Visual MODFLOW, which is based on the finite difference method, was se-lect ed for numerical simulation of groundwater flow. The reliable hydrogeological parameters were determined through model i-dentification and verification, and they were used to perform quantit ativeevaluation of groundwater resources in Chashang water source area. Nine designed pumping schemes were compared and the most reasonable groundwater pumping scheme was select-ed, and the allowable groundwater exploitation amountin normal and dry seasons was obtained as 6880 m3/d. Based on the pre-diction results, the currently designed groundwater exploitation amountis reasonable, which provides a basis for the reasonable exploration and utilization of groundwater resources in the study area.
