Abstract:

The desiccation of deep soil layer on the Loess Plateau results from the gradual depletion of storing water during the process of vegetation rehabilitation. The desiccation of deep soil layer related to vegetation rehabilitation on the Loess Plateau was reviewed, including its characteristics, types, quantitative indexes, contributing factors, distributions, harmfulness and countermeasures. Moreover, some problems and suggestions in the relevant researches were presented.

Key words: the Loess Plateau, desiccation of deep soil layer, vegetation rehabilitation, soil water
