Meanwhile, most aspects about this perspective are concerned, which include quantification of the soil water background of the plateau area, the regional spatial variation of soil water background and variation along the slope, mosaic structure and seasonal changes etc. the results show that : ( 1 ) for the fundamental circumstance for vegetation development is the original debilitated slope, so the perspective of soil water background specially for the loess plateau refers to the soil water conditions on the original slope. ( 2 ) the value of soil water background appears to be a descending trend from south to north based on the difference of vegetation zones. in the forest zone, soil moisture contents beneath 3m depth from the soil surface are more than 12 % usually ; in the forest - pasture zone, the values of soil moisture content beneath 4m depth underground are more than 6 % and stable, and tend to be ascending while the depth increases ; but the values in the dry pasture zone is lingering between 4 % to 6 % from the surface layer to sub - layers
