Abstract: The results of emergy analysis of different cropping system in Wuchuan County of Inner Mongolia under farmer view by using the emergy theory indicate that, the emergy input ratio and output ratio of cropping system are low level and should add output level; heighten the utilize ratio of renewable resource by strengthen the water saving because of the loading rate; The organically input overages the mineral input and we should increase assistant emergy to improve system production. The maize and rape has a exiguity higher proportion of yield emergy than other crops; we should increase the sowing area of maize and rape and decease the sowing area of potato according to the economics theory.
