摘　　要：在定边县东梁村一农户家院外选取Na Cl作为示踪剂,采用径向收敛水动力弥散实验理论方法进行了第四系松散沉积层的现场水动力弥散试验,计算了潜水含水层的弥散参数。结果表明,Na Cl作为示踪剂在苦咸水区也可取得明显的、良好的效果,填补了在苦咸水区选用Na Cl作为示踪剂的空白,同时也得出了该场地的纵向弥散度aL为0.812 cm,为进一步建立该地区地下水溶质运移模型、预测地下水污染的发展趋势和评价该地区地下水环境质量提供了重要依据,同时也为苦咸水区弥散试验示踪剂的选取提供了借鉴。Selecting Na Cl from Dongliang village of Dingbian county as the tracer, the hydrodynamic dispersion test of sediment of the Quaternary system is carried out and the dispersion parameters of groundwater aquifer are calculated. Results show that Na Cl has a good effect in the brackish water area as a tracer. At the same time, it obtains the longitudinal dispersion coefficient（aL） is 0.812 cm. It provides an important basis for solute transport model of groundwater, groundwater pollution prediction and the evaluation of the groundwater quality in the area, and provides a reference for the selection of tracer for dispersion test in the brackish water area.
