Abstract:: Effect of vegetation and restoration on shallow gully erosion has been researched in this paper,using survey data.The results show that once vegetation was restored,shallow gully trough occured sediment deposition,the deposition speed is 0.5era/a,undulation of cross section, in slope surfae was decreased caused by shallow gully sediment deposition,development of the slope surface inclined to level,After vegetation being destroyed,shallow gully erosion rapidly de-velops,amount of shallow gully erosion is 4400～7 600t/km²·a,it occupys above 47% of soil erosior amount on the slope surface.Washing width and depth of gully trough of shallow gully are 20～80cm and 10～30cm respectively.Compared reclaimed land after reclaimed 3 years with forest land,gully trough depth of shallow gully increases 40～60cm.The speed of shallow gully head back ward erosion is 3～5m/a,Because of development of lenth,width and depth of shallow gnlly,undulating of cross section in the slope surface increases,sheet and rill erosion increases, which intensifys development of shallow gully erosion,and undulating of cross section in the slope surface inclines to becoming big.
