摘　　要：本文根据泰安东武傍河水源地水文地质勘测资料,借助于地下水系统数值模拟软件包——Aqua3D,建立了水源地地下水水流和溶质运移模型,通过观测井实测水位资料率定了水文地质参数,进行模拟校正,所得拟合曲线显示建模的水位变化趋势和实测的水位变化趋势基本一致,拟合程度较高;选择两种不同开采方案,应用模型模拟,预测结果显示:主供水区承压岩溶水亚硝酸盐浓度满足城市饮用水供水要求,但水源地潜水及大汶口镇承压水水质受河流污染影响较大,对饮用水供水安全构成威胁。This article based on geohydrological exploration data in source of drinking wellfields nearby river in Dongwu of Taian, with the help of Aqua3D which is software used in numerical simulation of groundwater, built the source＇s model of groundwater current and solute moving. Made sure source＇s geohydrological constant by mensurating the water level in exploration logging, proofreader the parameter according simulation, then we got the fitting curve and the water level mutative trend revealed by the modeling was consistent basically with the metrical numerical value, they have great coherence. We chose two different exploitation projects and simulated by modeling, the forecast showed： the nitrite concentration in artesian karstic water can satisfy the request of city ＇s drinking water, but the quality of phreatic flow in headwater and artesian aquifer in Dawenkou town would have been polluted badly because of the pollution of the river, that will intimidate the safety of drinking water.
