Abstract: | The distribution of differently eroded soddy-podzolic soils on slopes of different gradients, lengths, and aspects has been studied with the use of a quantitative parameter of slope erodibility K. The latter is calculated as a product of slope gradient in the power of 1.3 and the length of the flow line (m) in the power of 0.5. It is shown that moderately eroded soddy-podzolic soils appear on the slopes of northern and northeastern aspects with K equal to 0.4; on the slopes of southern aspect, this parameter is somewhat lower (0.24). Moderately eroded soils prevail on the slopes of northern and northeastern aspects with K equal to 0.7. |
