摘　　要：羊庄盆地地下水资源丰富,近年来盆地内地下水硝酸盐污染呈加重趋势。基于Visual Modflow软件建立了盆地地下水水流与溶质运移数学模型,对羊庄断块地下水硝酸盐的迁移与扩散进行了数值模拟,预测了5 a和10 a后硝酸盐在地下水中的分布状况以及浓度变化趋势。结果表明:在预测时段,地下水中硝酸盐浓度呈明显上升趋势,模拟区硝酸盐浓度较高的地区主要分布在辘辘井区域,在地下水动力场的影响下,硝酸盐高浓度区域主要向西南方向扩展。氮肥的过量施用和盆地内养殖场粪便的随意堆放是地下水硝酸盐浓度持续增高的主要原因。Yangzhuang basin is rich in groundwater resources. In recent years,the nitrate pollution of groundwater in the basin has been aggravating. Based on the Visual Modflow,the numerical model of groundwater flow and solute transport in the basin was established,the nitrate migration and diffusion in groundwater at Yangzhuang fault block were simulated by this model which predicted the distribution of nitrate in groundwater and the variation trend of concentration after 5 a and 10 a.The predicted results show that the nitrate concentration in groundwater presents an obviously rising trend through the forecast period and the high nitrate concentration areas are mainly distributed in Lulujing.Under the influence of groundwater flow direction,the high nitrate concentration area mainly extends toward the southwest. The continuous increase of nitrate concentration in groundwater of Yangzhuang basin is mainly caused by farmers＇ excessive use of nitrogen fertilizer and the random discharge waste water from farms.
