On the relationship between environmental aridization of the Loess Plateau and soil water in loess
The similarity between loess palaeo- environment and geographic distribution of modem bioclimatic zones is taken as a starting point; the relationship between the environmental aridization and soil water in loess ia discussed from the point view of the soil water energy status and their soil water physical characteristics of modem lcessial soils on the Loess Plateau. The soil water content becomes less and less from southeast to northwest, which not only provides favorable conditions for dust production by wind of loess origin, but also reveals that there is obviously a directional change in the environmental drought intensity of the Loess Plateau.
