Abstract

The loess in Henan Province is composed of fine silt, silt and clay particles, among which, the content of silt particles is greater than 60% and clay particles usually is between 17.3%～32.6%. The rock soil property of the loess has decided the degrees of strong or weak of erosion. It is shown by the study that the new loess erosion is the most severe, the old loess comes second and palaeo-loess is lighter. The paper introduces the characteristics of soil erosion in different times and in different landform regions. It has put forward relevant suggestions on soil erosion prevention and control.
