Other Abstract

Soil anti-erodibility is one of the main factors affecting the development of soil erosion. The wide distribution of soil loss on slope
farmland in hilly loess region restricts the development of the local economy and the improvement of people's living standard seriously. As one
of the most severe soil erosion areas in china,it is especially important to research soil anti-erodibility characteristics of loess hilly region for
soil erosion prevention and control. Therefore,a field experiment is conducted to determine the soil anti-erodibility characteristics during the
growing stages of the soybean. Soil anti-erodibility index can reflect the characteristics of anti-erodibility effectively. Soil anti-erodibility index
increases significantly from the seedling stage to the bearing pod stage,reaches the maximum value at seed generative stage,and decreases
progressively from the seed generative stage to the seed-filling stage. The results show that the soil anti-erodibility of 0~ 5 cm layer is the best
and of >10~ 20 cm layer is the worst from the seedling stage to the branching stage. But the soil anti-erosion ability of >5~ 10 cm layer is the
best and of >10~ 20 cm layer was the worst from the blooming stage to the seed-filling stage. It shows that soil anti-erodibility index may be
closely related to the root distribution characteristics in soil. Soil anti-erodibility will be enforced with the increasing contents of roots in soil.
