What is the approximate total length of the starting and ending points of the Qinling Mountains?

The starting and ending points of the Qinling Mountains are about more than 1,600 kilometers long. They are the watershed between the Wei River, a tributary of the Yellow River, and the Jialing River and Han River, a tributary of the Yangtze River.

The Qinling Mountains can be roughly divided into three sections: west, middle and east. The western section is divided into three branches. The northern branch is Qinling, also known as Nanqishan or Dasanling; the middle branch is Fengling, which has loess accumulation and strong water and soil erosion; the southern branch is Zibai Mountain, which is called Chaiguanling in the northwest of Liuba. .

These mountains are all above 1,500 meters above sea level, with Zibai Mountain being the highest, with an altitude of 2,610 meters. The western section of the Qinling Mountains has become the watershed and origin of the Qingjiang River and the Jialing River, the left bank tributary of the Jialing River and the trunk and tributaries of the Jushui River, as well as some tributaries of the Bao River.

The climate of the Qinling Mountains:

The Qinling Mountains have a significant blocking effect on air flow. In summer, it is difficult for the moist ocean air to penetrate deep into the northwest, making the northern climate dry; in winter, it blocks the cold wave from invading southward, making the Hanzhong Basin and Sichuan Basin less susceptible to cold air. Therefore, the Qinling Mountains become the dividing line between the subtropical zone and the warm temperate zone.

The rivers south of the Qinling Mountains do not freeze, the vegetation is dominated by evergreen broad-leaved forests, and the soil is mostly acidic. To the north of the Qinling Mountains is the famous Loess Plateau. The average temperature in January is below 0°C, the rivers freeze, the plants are mainly deciduous broad-leaved trees, and the soil is rich in calcium. The Qinling Mountains and the Bailongjiang River Basin still preserve contiguous forests and contain rare animals and plants.
