Dynamics of grazing ecosystem was about the interaction with plant and animal production, herbage output that changed with the season had effect on the animal feed and the capacity of transforming the food to animal nutrition. During the spring summer and autumn, the content of the herbage was separately more 15.99%、0.43% and 2.7% than of the grass lived on the land. However the protein content was lower in the winter. The protein intake in spring was more 22.3% of that during the summer. The protein content of herbage was the highest during the spring, but the DM intake of the sheep was fewer, which resulted in the loss of weight during the winter and spring.
