the distribution of soil ferility in Zhifang gully watershed is studied
The result shows①soil and water loss plays an important role in the impacting of land use
vegetation andartificial soil improvement on loess soil fertility;②soil and water loss also plays an important roleon the formation of main soil types;③the fertility distribution in the profile of loess soil
whichgrows on Heilu soil
is completely different from Heilu soil;④the fertility distribution in thewhole slope land of loess soil has the different propertys
namely
the fertility on upper slope ismore than that on down-slope
