The area of hilly region in Pingdingshan is 2 607.36 km2 and is about 29.6% to total land area.Gully density and soil and water loss is very high in this region.Gully head is the place of erosion occuring.Gully protective system is the main component of small watershed comprehensive control.However,in actural control,the quality of gully head protective system is low and absent vegetative measures disposition.Our research use different treatment of economic vegetation and get lots of data of rainfall,gully head advancing,gully cutting,soil erosive yield,biomass,soil nutrient.After analysing,the optimum disposition of vegetative measure for gully head protecting in Pingdingshan is found.The aim of this paper is using simple,economic vegetation protective approach to control runoff crushing to gully slope,and provide scientific base for gully head protection in hilly region.
