Abstract:
To study on water-salt transport regulation in the arid and inland region,it is benefit for rational utilizing water resources,reducing no-effective phreatic water evaporation,preventing saline-alkali soil.According to the principle of water balance and salt balance,the paper develops a soil water and salt balance model to study soil water-salt transport regulation in the arid and inland region.The accuracy of the model depends on the accuracies of the precipitation,evaporation,irrigation water,salt,etc.
