Based on analysis of 137Cs activities in soil profiles on hill slope of different slope lengths in the Loess Hilly Area in China
the spatial variance of erosion was studied. The results show that the slope length has great impact on the spatial distribution of the soil erosion intensity
and the soil erosion intensity on loess hill slope was in a fluctuating tendency. In the influx process of runoff in a small watershed
net soil loss intensity increased first and then decreased with flow distance.
