摘要 干旱区新建灌区的水盐动态是其环境变化的主要影响因素 ,也是影响灌区正常发挥效益的关键问题 ,因此 ,预测水盐动态对于环境保护和灌排方案的制定显得尤为重要。以土壤饱和与非饱和流的水动力学方法为依据 ,采用一维流与二维流数值模拟相耦和的方法 ,建立起了秦王川灌区水盐动态模拟模型 ,预测了灌区通水后设计运行方式下未来2 0年的水盐动态。可为灌区制定排水方案。 In drought irrigation area, water salt dynamic is one of the main factors effected to the environment changes. It also is a key element effecting to the benefits of irrigation project. Water Salt dynamic forecasting is of great importance to the environment protection and the formulation of irrigation drainage program. According to the hydrodynamic of saturated soil and unsaturated soil, a mathematics simulation method with one dimensional and dual dimensional flow is provided, and a simulation model of water salt dynamic in the irrigation area is established. This model forecasted the water Salt dynamic after 20 years operation and got satisfactory result for planning and effective operation. [
