we studied the spatial distribution of soil nutrient components in dif ferent grass sloping lands in the Yunwu Mountains. Results showed that in the horizontal direction
southern slopes and bare lands had a similar distribution of soil organic C and total soil N in surface soils( 0-15 cm)
whereas nor thern slopes had an opposite distribution pattern. Additionally
total P varied greatly along sloping lands regardless of slope direction. In soil profiles
soil organic C
to tal N
mineral N
Olsen P
and CEC were all decreased with soil depth and followed the order of nor thern slope > southern slope > bare land
yet pH values presented contrary distribution pattern. The distribution of available K varied with slope type
while total P changed slightly with soil depth. Both soil proper ties followed the order of bare land > norther n slope > southern slope. Our results suggest that soil nutrient conditions can be improved by natural re-vegetation and the improvement of soil nutrients are more obvious in northern slope than southern slope.
