Abstract: According to the principle of harmonious development of integrated farming system, based on material and energy flow and economic value flow in the existing agriculture system in consideration of restrained factors of land area, manpower, livestock power, social demand and fodder amount in the investigation area, an optimization structure was suggested. In the light of the optimization model, the total net profit of farming and animal husbandry can be 69 14% more than that of conventional one, and the system's comprehensive profit index can be increased by 33.48%, which indicated that this optimization design can provide significant benefits for adjusting the structure of agriculture system in the investigation area.

Key words: agricultural ecosystem, combination of farming and animal husbandry, optimization
