干旱内陆灌区土壤水盐模型

Soil water and salt balance model for irrigation district in arid and inland region

  • 摘要: 研究干旱内陆区土壤水分运移规律以及土壤盐分运移规律,有助于合理利用水资源,减少潜水无效蒸发,防止土壤盐碱化。根据水量平衡和盐量平衡原理,建立了土壤水盐模型,计算土壤水盐迁移量,并对干旱内陆区土壤水盐运移规律做了初步研究。

     

    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.
