Abstract: In order to discuss the character and advantage of emergy flow, the emergy input and output of optimization model of farming and animal husbandry were analyzed with emergy analysis method, and its indexes of resource utilization, environmental stress and sustainable development were evaluated. Compared to the traditional agricultural model, results showed that, the optimization model had higher production efficiency, more advantageous in price-competition, more powerful self-development and lower environment pressure. So the optimization model was the more potential model for development in the region.
