Abstract Based on the past 50 years' harnessing achievement and experience of the Loess Plateau, the soil and water conservation in the Arid or Semi-arid region has been re-analyzed. It indicates that the reduction of runoff from soil and water conservation should not be neglected, arbor plants should be planted moderately, relation between the engineering works of gully and the biological measures of the slope land is interdependent. Water and soil loss in construction of fundamental facilities should be prevented as soon as possible in the great development of western China. In the view of the whole watershed, soil and water conservation with water-saving is advocated, and the harnessing emphasis might be the sedimentary and coarse-sediment area on the Loess Plateau. According to community characteristics of vegetation and zone distribution theory, it is necessary to adjust measures to local conditions in afforestation and grass planting, choose grass or trees enduring drought and barren but high water-consuming vegetation, construct drainage installation in check dams with different scale for sediment and drainage.
