摘　　要：本文运用GMS软件,以巨淀湖湿地及其周边区域为研究区,建立了地下水流和溶质运移模型,并进行模拟预测。结果表明:研究区地下水位观测资料与水流模型的模拟水位拟合结果较好。硝酸盐污染质主要集中在研究区南部区域,典型污染质迁移中以椭圆伞状由污染源处向研究区中部扩散迁移,在漏斗区产生聚集。污染质运移中不同浓度区间确定的影响范围随时间推移增加的速率在减小,到一定时间趋于稳定。该研究为湿地生态系统的污染防治提供依据,为黄河流域湿地的保护修复提供了范例。In this paper,by using GMS software,taking Judian Lake Wetland and its surrounding areas as the study area,a groundwater flow and solute transport model has been established,and simulation prediction has been conducted.It is showed that the groundwater level observation data in the study area and the simulated water level of the water flow model have good fitting results.Nitrate pollutants are mainly concentrated in the southern part in the study area.In the typical migration of pollutants,they diffuse and migrate from the pollution source to the middle of the study area in an elliptical umbrella shape,and gather in the funnel area.The rate of increase of the influence range determined by different concentration intervals in the migration of pollutants is decreasing over time and tends to be stable after a certain period of time.This study will provide a basis for the pollution prevention and control work of the wetland ecosystem.It will also provide a model for the protection and restoration of wetlands in the Yellow River Basin.
