不同灌溉条件下土壤含水量蒸发的研究

Study on the Soil Moisture Evaporation under Different Irrigation Condition

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,该绿洲灌区水均衡模型可反映灌区水分运动,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 different moisture movement in irrigated area under different irrigation condition, agricultural areas in oasis irrigated area were divided and model was created according to the different irrigation methods. This paper analyzed four-water transformation relationship between water diversion agriculture area and well irrigation farming areas, and moisture migration from water diversion grain-growing areas to non-agriculture area and well irrigation farming areas by using this model and four-water transformation theory. The water balance model of oasis irrigation area can reflect the irrigation water movement in irrigated area, and is suitable for study on moisture movement irrigation area with different water diversion ways.
