The comparison of the effects of two approaches to control gully erosion in the Black Soil Region of China

Gully erosion is an important form of soil erosion, however, little was done on the effect of gully erosion controlling approaches. A program for controlling gully erosion was carried out in Heshan Farm in black soil region of northeast China from 1994 to 1996 include two approaches: "Soil fill" and "Vegetation cover". From the investigation at 2009, Soil fill approach can protect the original place of gully erosion well, but this apporach ignores the whole impact at the catchment scale, and may cause to new gully appear. "Vegetation cover" approach is better to control gully erosion than "Soil fill" approach, but has little effect on controlling the headcut retreat
