Qinling Mountains are divided into narrow Qinling Mountains and broad Qinling Mountains. In a narrow sense, Qinling Mountain is limited to the mountain range between Weihe River and Hanjiang River in the south of Shaanxi Province, bordering Bahe River and Danjiang River Valley in the east and Jialing River in the west. The Qinling Mountains in a broad sense, which starts from Kunlun in the west, passes through Longnan and Shannan, and reaches Dabie Mountain in Hubei, Henan and Anhui and Zhangbaling near Bengbu in the east, is the watershed of the Yangtze River and Yellow River basins.
Qinling Mountain is not only the boundary mountain between north and south of China, but also the boundary line between north and south in geography, climate and resources. Different climate, different soil and water, different social habits such as diet, architecture and transportation have evolved into different social customs over time.
Because the temperature, climate and topography in the north and south of Qinling Mountain show different changes, the Qinling-Huaihe River line has become the most important geographical dividing line between north and south in China. In winter, Qinling blocks the cold wave from entering the south; In summer, the humid sea breeze is blocked from entering the northern region. The Qinling Mountains and Huaihe River basins are the transitional areas between rainy in the south and drought in the north. From the vicinity of Huaihe River in Qinling Mountains to the north, the rainfall decreased sharply.
Qinling section
West section 1
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.
2. The middle part
The middle part of Qinling Mountains in Shaanxi Province is called Zhong Nanshan. The main mountain ranges are Sifangtai, shouyangshan, Zhong Nanshan and Dongguang Bald Mountain, all of which are between 2,500 and 3,000 meters above sea level. It is the birthplace of Fenghe River, Laohe River, Chanhe River, Woods River, Xunhe River and Qian Qian River. Pingheliang, extending from Qinling Mountain to the southeast of Kunming, has Guangdong Mountain as its main peak, with an altitude of 2,675 meters.
Mount Li is a fault-block mountain at the northern foot of the middle Qinling Mountains in Shaanxi Province. The main peak is Renzong Temple, with an altitude of1302m. Some streams from Lishan Mountain become tributaries of Bahe River, and some directly flow into Weihe River.
3. Eastern Sector
The eastern part of Qinling Mountain in Shaanxi Province is finger-shaped and spreads to the southeast. From north to south: Taihuashan, Mangling, Liu Ling, Mangshan and Xinkailing, all at an altitude of 1500-2600 meters; Nanluo River, Danjiang River and its tributaries, Yin Hua River, are distributed among them, becoming mountainous and valley topography. Caolianling and Taihuashan, the main ridges of Qinling Mountains, are the watershed and birthplace of Danjiang, Nanluohe and Shanxi on the northern slope of East Qinling Mountains.
