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 Mountain, also known as Nanqi Mountain or Dashanling Mountain; The middle branch is Fengling, with loess accumulation and strong soil erosion; The south branch is Baizi Mountain, which is called Chaiguanling in the northwest of Liuba.
These mountains are all above1500m, and Baizi Mountain is the highest, with an altitude of 26 10/0m. The western part of Qinling Mountain has become the watershed and birthplace of Qingjiang River and Jialing River respectively, a tributary of the left bank of Jialing River, a main tributary of Qushui River and a part of Baohe River.

Climate of Qinling Mountains:
Qinling Mountain has obvious blocking effect on airflow operation. Summer makes it difficult for humid marine air to penetrate into the northwest, making the climate in the north dry; In winter, the cold wave is prevented from invading southward, which makes Hanzhong basin and Sichuan basin less affected by cold air. Therefore, Qinling Mountain becomes the dividing line between subtropical zone and warm temperate zone.
The rivers south of Qinling Mountains are not frozen, the vegetation is mainly evergreen broad-leaved forest, and the soil is acidic. To the north of Qinling Mountains is the famous Loess Plateau. The average temperature in 65438+ 10 is below 0℃, the rivers are frozen, the plants are mainly deciduous broad-leaved trees, and the soil is rich in calcium. The Qinling Mountains and Bailong River basins still preserve continuous forests and precious animals and plants.
