What are the characteristics of Tianshan pasture in Xinjiang?

Analysis: Xinjiang is an important animal husbandry base in China, and Tianshan Mountain is the main pastoral area in Xinjiang. Tianshan grassland extends vertically and has four distinct seasons. In summer, lush pastures grow on the uphill of Tianshan Mountain, where herders drive horses, cattle and sheep to graze. In autumn, herders drive their cattle from alpine summer pasture to alpine pasture for winter. Therefore, compared with other pastoral areas in China, Xinjiang Tianshan pastoral area has the characteristics of rotational grazing on the mountain and under the mountain.
