| Abstract: | 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.
