摘　　要：考虑了灌区的社会、经济和水资源等系统，采用模拟技术，建立了灌区地面水与地下水联合优化调度的模拟模型，并以泾惠渠灌区为实例，预测了灌区的需水量、来水量、供水量，并通过模拟模型计算及灌区水量供需平衡分析，得出在一般干旱年，河流径流比较丰沛，地下水供水量占总供水量的25％左右，地下水可以得到补充涵养；在干旱年或特旱年，地下水供水量占总供水量的30％左右，可以利用地下水库进行水量调节，地下水主要依靠丰水年的地面水及灌溉渗水进行补充涵养，以确保灌区水资源的可持续利用。The article has been considered the systems of society, economics and water resources, using the simulation technology, established the simulation model of optimal distribution combined surface water with groundwater. As Jinghuiqu ID for the example, has forecasted the irrigation requirements and the intake of river water source, the intake of river water source and the water supply volume. Moreover by the calculation of simulation model and balance analysis of water supply with irrigation requirements, obtained the conclusion that in the general drought year, the runoff in river source was rather abundant, the groundwater supply only account about 25% of the gross water supply, the groundwater source can be refilled; In drought year or special drought year, the groundwater supply account about 30%, the groundwater reservoir can be used for water volume adjustment, the groundwater complement major depend the surface water in rich water year and irrigation seepage water. So enhancing the united regulation of groundwater with surface water will be infected the water resources distribution in a bigger region, ensured sustainable utilization of the water resources in IDs.
