为改善松原灌区规划区盐碱化现状、防止灌区运行后土壤发生次生盐碱化的目标,对灌区地下水、地表水联合调度进行模拟,以盐碱化临界埋深为标准并结合水盐均衡差对模拟计算结果分析后表明,采用考虑实际条件的井渠结合灌溉方案既能淋滤土壤中的盐份又有效地控制潜水埋深减少土壤返盐,兼顾生态环境效益与经济效益。
In order to improve the status of salinization in the planning area of Songyuan Irrigation District and prevent the occurrence of secondary salinization of soil after the operation of irrigation district, the joint operation of groundwater and surface water in the irrigation area was simulated. Based on the salinity threshold depth and the combination of water and salt balance The analysis of the results of the simulation shows that the well and canal combined with irrigation scheme considering the actual conditions can not only leach the salt in the soil but also effectively control the depth of the diving and reduce the salt return of the soil, taking into account the ecological and environmental benefits and economic benefits.
