摘要

Soil erosion always leads to decreasing of land productivity, deposition of channels, lakes and reservoirs, pollution of water quality and so on. In the small watershed management, the soil erosion amount should be definite. The erosion modulus is able to quantitatively characterize the average extent of soil erosion. In practice, it is difficult to ascertain the erosion modulus. Several methods to ascertain erosion modulus are introduced in this article. Taken some small watershed of Yellow River in West Henan region as an example, these methods are testified to be feasible in ascertaining the erosion modulus. In the construction of small watershed dam system projects and planning and design of hydro junctions, methods and thoughts can be provided for the determination of the erosion modulus.
