英文摘要	Based on the measured data of soil and water loss in the monitoring stations in different relief areas in Zhangjiakou, the spatial suitabilities of water and soil conservation measures were researched. The results showed that, in different relief sections of the sloping lands, the benefits of water and soil conservation for level terrace was the highest, which was larger than 90%, and that for the planted grass was the lowest, while that for the economy forestry was the median. For the waste land, the benefits of vegetation measure combined with level trench and/ or fish-scale pits, over 75%, was the best, those of natural restoration and planted grass measures occupied the median level with large spatial and temporal differences, and the main reasons could be attributed to the diversities of vegetation quality and soil properties. During the initial period of closure measure to controling soil and water loss, eco-recovery must depend on engineering measures to provide growing environment to vegetation.
