The study of the distribution of soil loss on loess slope is a theoretical base to understand the mechamism of soil loss and control soil loss effectively. In order to study the mechamism of soil loss on different segments and the development of erosion configuration for different slope length, simulated artificial rainfall experiments of different slope length (2.5,5,7.5, 10m) for different rainfall intensity (0.72,1.16,1.4,2.0,2.4mm/min) were conducted. The results showed that under the experimental condi...
