英文摘要	Study on the compound farming pattern of grain-cash crop-trees in slope croplands for continuous six years shows that the grain-cash crop-trees compound farming makes the soil moisture content increase and has prominent water holding effects. This farming pattern is based on the poly-soil ridge planting and the agroforestry, and plays an important role on increasing the systematic output, reducing the runoff, controlling the soil erosion and lessening non-point source pollution on the basis of fewer inputs. Also, the compound farming of grain-cash crop-trees can better soil structure effectively in slope croplands and advance the content of soil nutrient.The physical barrier effect of the compound farming pattern can hold soil runoff and reduce sediment loss; thus, it improves the content of soil nutrient. The soil porosity of the compound farming pattern of grain-cash crop-trees is 9.38 percent higher than that of the compound conventional tillage pattern of grain-cash crop-trees and the former adds the soil particle content which diameter is less than 0.02mm. The compound farming pattern of grain-cash crop-trees has notable soil and water conservation effect and high economic benefit, so, it is suitable for the slope cropland use model in Three Gorges Reservoir Area widely.
