According to the principle of harmonious development of planting and animal husbandry, a typical farmer of Honghu Village Yujiang City in Jiangxi Province was taken as the research object; an optimization model consisting of upland-subsystem, pig-feeding-subsystem and manure-treatment-subsystem was suggested. In the light of the optimization model, the pure input of the farmer increased by ￥7 118.7 than that of conventional one and 50% of pig manure was fixed in the system. Higher economic benefits, eco-benefits and social benefits could be received under this optimization model and at the same time it can provide significant benefits for adjusting the structure of agriculture system in the investigated area.
