The Qinling Mountains, which begin and end at a total length of about 1,600 kilometers, are the watershed between the Wei River, a tributary of the Yellow River, and the Jialing and Han waters, tributaries of the Yangtze River.
The Qinling Mountains can be roughly divided into three sections: western, central and eastern. The western section is divided into three branches, the northern branch is the Qinling Mountain, also known as the South Qishan Mountain or Dasanling; the middle branch is the Fengling Mountain, which has loess deposits and relatively strong erosion; and the southern branch is the Zibaishan Mountain, which is known as the Chaikuanling Mountain in the northwest of Liuba.
These mountain ranges are all above 1,500 meters above sea level, and Zibaishan is the highest, with an altitude of 2,610 meters. The western part of the Qinling Mountain becomes the watershed and birthplace of the Qingjiang River and the Jialing River, the left bank tributaries of the Jialing River and the dry and tributaries of the Discouragement River, as well as some tributaries of the Berg River, respectively.

Climate of the Qinling Mountains:
The Qinling Mountains have a significant blocking effect on the operation of air currents. In summer, it is not easy for the humid ocean airflow to penetrate deep into the northwest, so that the northern climate is dry; in winter, it blocks the southward invasion of the cold wave, so that the Hanzhong Basin and the Sichuan Basin are less subjected to cold air invasion. Therefore, the Qinling Mountains have become the demarcation line between the subtropical and warm temperate zones.
South of the Qinling Mountains rivers do not freeze, the vegetation is dominated by evergreen broad-leaved forests, and the soil is mostly acidic. North of the Qinling Mountains is the famous Loess Plateau, where the average temperature in January is below 0℃, rivers are frozen, vegetation is dominated by deciduous broad-leaved trees, and soil is rich in calcium. The Qinling Mountains and the Bailongjiang River Basin still preserve continuous forests with precious animals and plants.
