Abstract: After the settlement of herdsmen, which utilization model should be adopted for seasonal pasture under the current productivity remained an unsolved problem. Based on the principles of forage animal balance and high efficient and sustainable energy utilization, this paper proposed an optimized model of temporal spatial disposition in the seasonal pasture of Axili kazakzuxing of Changji city, a typical place in the middle section of the northern slope in the Tianshan mountains in Xinjiang(grazing in warm season; grazing and house feeding in cold season), which not only achieved forage animal balance, protected and improved ecological environment, but also achieved good economical and social benefits.
