Abstract: Soil and water loss is the serious ecological problem in the arid and semi-arid areas. Therefore, adoption of efficient soil and water conservation measures is the primary task for both the optimal utilization of natural resources and environmental protection within these regions. However, considering the complex process of water and soil loss in multiscale watershed areas it is difficult to establish the optimal land rehabilitation plan for the whole watershed area. This paper developed a cellular automata model to fast and efficiently generate landscape pattern for the watershed area in consonance with the sustainable development goals. Then, corresponding to these different landscape pattern the soil and water loss risk was assessed. The developed approach was applied on a small watershed in Loess Plateau, China, where some management practices for soil and water conserve were adopted for the past decade and there still exists some problems. The results indicated the developed approach could fast and efficiently generate optimal management scenarios and assess the influence of different land restored measures on regional soil and water conserve.
