Abstract: Based on existing research findings and related data available,scenario analysis was carried out of the Changchuan Watershed in the feldspathic sandstone area in the middle reaches of the Yellow River to explore effects of different erosion control strategies and the "Grain for Green" strategy on soil erosion.Results show that biological and engineering measures are quite significant in erosion control effect,whereas the "Grain for Green" strategy is not so comparatively.Combination of the two makes the effect greater and is recommended to be the priority choice for soil erosion control in this region.

Key words: soil erosion, scenario analysis, middle reaches of the Yellow River, feldspathic sand-rock area, Changchuan Watershed
