Based on the monitoring data of soil and water loss in typical small watersheds and the demonstration areas of Zhangjiakou City

the integrated management mode of soil and water loss and its potential benefits were studied in different erosion zones.The results show that for the reconstruction of land use and the selection of engineering and biological measures

the underlying differences between shady and sunny slopes should be accounted for the hilly and rocky mountainous areas

the thickness of the soils in different locations of small watersheds should be considered in the mountainous area

and in the cretaceous terrain area

minimization of the disturbances and breakdown of original ground surface should have the highest priority.Both the typical small watersheds and the demonstration areas which already conducted comprehensive management obtained considerable amount of ecological benefits

the benefits of sediment trapping and water storage reached as high as 70%and 60%for the small watersheds

and both over 60%in the demonstration areas

respectively.At the same time

the vegetation cover percentage and land use ratio increased significantly

resulting in improved capability to control soil erosion.
