It starts from the south of Gansu Province in the west and passes through the southwest of Shaanxi Province to the west of Henan Province. It is the watershed of Weihe River, Jialing River and Yangtze River tributary [[Han River]] of the Yellow River. Length 1 100 km. The western part of Qinling Mountain in Gansu Province is relatively low, with the highest peak about 2000 meters above sea level. There are Chengxian, Huixian and Liangdang basins in the mountains.

Qinling Mountain is the geographical dividing line between north and south of China. It has obvious blocking effect on airflow operation. The humid maritime airflow in summer is not easy to penetrate to the northwest, which makes the climate in the north dry; In winter, cold air is prevented from invading south, and Hanzhong basin and Sichuan basin are 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. In the north is the Loess Plateau. The monthly average temperature of 1 is below 0℃, rivers are frozen, 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. Foping is one of the habitats of giant pandas.
