黄土区坡地土壤水分运动与转化机理研究进展

Review on hillslope soil water movement and transformation mechanism on the loess plateau

  • 摘要: 土壤水分是作物生长、植被恢复以及生态环境建设的主要限制性因素.从降雨入渗及再分布、土壤水量转化以及土壤水分动态变化等几方面概述了黄土区坡地土壤水分运动与转化研究进展,认为应该把坡面土壤—植物—大气作为一个物理上的连续统一体,以大气水、地表水、植物水和土壤水相互转化过程和机制为基础,研究坡面土壤—植被—大气界面水分运动和转化规律,为植被恢复重建提供理论依据.

     

    Abstract: Soil water is the primary limiting factor for crop growth,vegetation rehabilitation and eco-environment construction Hillslope soil water movement and transformation is reviewed,including rainfall infiltration and soil water redistribution,soil water transformation,and soil water dynamic change For a successful project of vegetation rehabilitation,soil-plant-atmosphere on the hillslope should be considered to be a physical continuum,and its interfaces of water movement and transformation should be studied based on the processes and mechanisms of atmospheric water,surface water,plant water,and soil water.
