Abstract: Soil deg radatio n is one of the most serio us environment problems in the wo rld, which threatens the human existence
directly . A mong those facto rs w hich cause soil deg radation, soil erosion is the mo st popular and important facto r. Based o n the
predecesso rs. achiev ements of so il degradation by erosio n, the authors briefly review the develo pment status o f so il degradation
by erosion, especially in its mechanism, and then put forward the measures t o prevent and control so il erosio n pert inently.
