One-dimensional water-salt movement under different conditions of irrigation and drainage was simulated by using HYDRUS-1D model. The effects on the reclamation of saline-alkali soil of conventional irrigation,water-saving irrigation,pipe drainage,and drainless condition were compared and evaluated.
利用HYDRUS-1D模型对不同灌排模式下土壤水盐运移进行一维数值模拟,分析比较了节水灌溉和常规灌溉、暗管排水和无排水对盐碱地的改良效果。
