摘要
根据不同灌水方式灌区水分运动不同的特点,对绿洲灌区的农区部分按不同灌水方式进行分区,建立模型;并运用该模型和四水转化理论,分析了引水农区和井灌农区的四水转化关系和引水农区向非农区、井灌农区的水分迁移;讨论了农区水分在不同时期的转化与消耗。结果显示:该绿洲灌区水均衡模型可很好反映灌区的水分运动,它适于研究不同引水方式共存的灌区的水分运动。
According to the characteristics of the water movement of different irrigation methods in irrigation areas in oases, the irrigation area is divided into two research areas based on different irrigation methods, and a model is established. The dissipative hydrological theory is analyzed by using this model. At last, the water consumption of irrigation areas is discussed in different periods. The analytical results show that the irrigation area can be divided into these two areas, and this model can be applied to research on the water movement of the irrigation area which have different irrigation methods.
