Abstract: On the basis of rational distribution of forest,grassland and fruit garden in agroecosystem, the agroeco-logical environment of hilly upland cropping area is improved by readjusting land utilization structure,ex-panding vegetative land area and optimizing breeding structure.None—productive outputs of energy andmaterial are reduced, system mechanisms are improved,and a favorable cycling of grass—animal hus-bandry—soil fertility is established.Cereal and bean yields, total social outputs and per capita income areincreased by 95.59%,1.8 times and 3.1 times respectively.
