Time Law of Herdsmen's Changes in Tianshan Mountains

Regularity of the transition time of herdsmen in Tianshan Mountains: The Altai Mountain in the north, the western mountainous area of Junggar and the northern slope of Tianshan Mountains rotate grazing in four seasons, that is, spring and autumn pastures in low mountains, hills and piedmont plains, summer pastures in high mountains, subalpine mountains and forest meadows, and winter pastures in middle and low mountains, plain valleys and desert areas.

The Pamir Plateau, Kunlun Mountain and the southern slope of Tianshan Mountain to the south are grazing in rotation in four seasons, that is, grazing in high mountain areas in summer and autumn and grazing in middle and high mountain areas in winter and spring. However, in the marginal meadow and valley meadow areas of Junggar Basin and Tarim Basin, the climate is more stable and warmer than that of alpine region all the year round, and grazing can be carried out in all seasons.

Characteristics of Tianshan Mountain:

Tianshan Mountain is one of the seven mountain systems in the world, located in the hinterland of Eurasia, the largest land on earth. It spans China, Kazakstan, Kyrgyzstan and Uzbekistan from east to west, with a total length of 2,500 kilometers, an average width of 250-350 kilometers from north to south and a width of over 800 kilometers at its widest point.

Tianshan Mountain is the largest independent zonal mountain system in the world, the farthest mountain system from the ocean in the world and the largest mountain system in the global arid area.

Tianshan Mountain runs east-west, stretching for 1.7 thousand kilometers in China, covering an area of over 570 thousand square kilometers, accounting for about 1.3% of the total area of Xinjiang. The Tianshan Mountains in China roughly divide Xinjiang into two parts: the Tarim Basin in the south and the Junggar Basin in the north. Turpan basin lies between its eastern branches. The long-low temperature residual vein in the east reaches Jiayuguan.
