摘　　要：简述了我国北方地区近年来开展的地下水环境地质调查与评价工作,阐述了进行区域地下水浓度场绘制时需要考虑的主要因素、评价方法及基于ArcGIS的计算机实现步骤。结果表明:考虑了水文地质单元分区、地下水流向、溶解组分分布类型的评价方法更合理,结果更符合实际。以北京平原区为例,选取总硬度、总Fe含量进行了区域地下水水化学场刻画,并进行了浅层地下水的TDS单因子和综合质量评价。The groundwater investigation and evaluation of environmental geology works carried out in northern China in recent years were described firstly. Then several main factors,which should be taken into account when drawing regional groundwater concentration field,evaluation method and implementation steps in Arcgis were presented. The study results show that the evaluation methods including the hydrogeological unit partition, direction of groundwater flow and distribution of dissolved species are more reasonable. In the end,this method was applied in Beijing Plain area to map the regional groundwater chemical field of total hardness and total Fe,also the application in regional quality assessment of TDS and compre-hensive evaluation based on 10 species show this method is well.
