摘　　要：为了减少引用地表水量,充分利用地下水以实现节水的目标,针对新疆克孜河下游平原区伽师县新垦58团盐碱化严重的现象,采用井渠结合的灌溉排水模式。利用M odflow对确定典型区的地表水、地下水联合调度进行模拟,并对区内水源地开发规模进行模拟预测,得到区内合理的地下水开采规模,实现地下水控制到临界深度,减少土壤返盐,减少潜水无效蒸发,提高用水效率。In order to decreasing the utilization volume of the surface water,realizing the aim for saving water by fully using groundwater. For serious phenomena of salinization at the newly cultivated 58 corps in Jiashi county of the downriver plain region of Kezi river in Xinjiang. It adopts the irrigation and drainage water pattern which combines the well and trench. Applying MODFLOW to carry on the simulation which unifies and control the surface water and ground water in the typical：area, and to carry on the simulation forecast in the development range of the wellhead area, obtains reasonable exploitation scope of groundwater, controls groundwater to critical depth, reduces accumulation of salt in the surface soil, reduces the diving invalid evaporation and promotes the efficiency water to be used.
