Abstract：By analyzing and assessing typical watersheds and the current modles of soil and water conservation in the gully and rolling loess region, the study preliminarily defines the key measures and combination of comprehensive control of soil erosion and water loss in types of erosion areas. The combination proportions in different types of erosion areas are seen as 18% to 25% for terrace, 45% to 55% for the planted forest, 20% to 25% for planted grass, 5.5% to 7.5% for the dam land and 0.5% to 2.7 % for the irrigated land in the 1 st and 2nd sub-region. and the combination proportions for terrace, planted forest and grasss are 42% to 48% , 32% to 38% and 18% to 22% respectively in the 3rd sub-region, In the 4th and 5th sub-regions these for terrace, planted forest, grass, dam land and irrigated land are 28% to 35% , 40% to 46% , 13% to 17% , less than 5% and 6% .respectively.
