Qilian Mountains (the mountains on the border of northeast Qinghai Province and West Gansu Province) generally refer to Qilian Mountains

Qilian Mountains, located in the northeast of Qinghai Province and the western border of Gansu Province, is one of the main mountains in China. It is composed of many parallel mountains and wide valleys with northwest southeast trend. It is 800 kilometers long from east to west, 200-400 kilometers wide from north to south, and 4000-6000 meters above sea level. There are 3306 glaciers, covering an area of about 2062 square kilometers.

The west end is at Dangjin pass, which connects with the Altyn Mountains. East to the Yellow River Valley, and Qinling, Liupanshan connected. It is nearly 1000 kilometers long. It belongs to fold fault block mountain. The widest is between Jiuquan City and Qaidam Basin, up to 300 km.

The mountains range from northwest to Southeast, including Daxue mountain, Tuolai mountain, Tuolai mountain, YEMA mountain, Shule mountain, Danghe mountain, turgen Daban mountain, Chaidamu mountain and Zongwulong mountain. Most of the peaks are 4000-5500 meters above sea level. Tuanjie peak, the highest peak in shulenan mountain, is 5808 meters above sea level. Mountains above 4000 meters above sea level are covered with snow all the year round, and valleys between mountains are between 3000 and 3500 meters above sea level.

Qilian Mountain, known as "Wanbaoshan", contains a wide range of high-quality minerals, including asbestos, pyrite, chromite, copper, lead, zinc and other minerals. Babaoshan asbestos is a rare raw material for wet spinning in China. The cold and humid climate in Qilian mountain area is favorable for the growth of forage. In the area above 2800 meters above sea level, there are large grasslands, which provide a good place for the development of animal husbandry.

Since 2017, China has started the pilot work of establishing Qilian Mountain National Park in the Qilian mountain area.

The origin of the name

Qilian Mountain originally refers to the northernmost mountain range in the south of Hexi Corridor (the west end of the south mountain of the corridor, with an altitude of 5547 meters), or "Qilian Mountain" in a narrow sense. "Qilian" is Xiongnu language, Hun Hutian is "Qilian", Qilian mountain means "Tianshan". Because it is located in the south of Hexi Corridor, it was also called Nanshan in history, as well as Xueshan and Baishan. In the early years of the Western Han Dynasty, Huo Qubing went to the West and conquered the Xiongnu, "if I lost Qilian Mountain, I would not have enough livestock; if I lost Yanzhi mountain, I would have no color to marry." This is the "Qilian Mountain" referred to in Xiongnu folk songs. Later, it generally refers to a series of mountains which are connected in geology or geomorphology between Gansu and Qinghai.

Corridor Nanshan, because it is located in the south of Hexi Corridor and named. According to the geological records of Qilian Mountain, Lenglongling is also classified as the south mountain of the corridor. However, most maps and geographical works have defined Lenglongling separately, that is, Lenglongling and South Corridor mountain are the first grade mountains of Qilian Mountains. The south mountain of the corridor is located in the north of Heihe River in Qinghai Province, reaching the provincial boundary in the north; it starts from the source of fengluochuan in the west, and ends near Qilian County in the East. It extends 160 km in Qinghai Province, 10-20 km in width. The peak elevation is generally between 4000-4500 m, and the highest peak is chaidanuo mountain, 4764 m above sea level.

Wushaoling is the southeast end of Lenglongling, which is the westernmost end of East Asian monsoon and the natural boundary between Longzhong plateau and Hexi corridor. It is the boundary of the first and second step of China's topography, the dividing line between the monsoon region and the non monsoon region, the inner flow region and the outer flow region, the intersection of the Loess Plateau, the Qinghai Tibet Plateau and the Inner Mongolia Plateau, and the dividing line of the transition from the semi-arid region to the arid region.

Tuolai mountain means "mountain with firewood" in Mongolian. It's also called Mulei mountain. There are also Taolai mountain, Tuole mountain, Taolai mountain and other names.

The mountain peaks are generally between 4000 and 4500 m above sea level, with the highest peak at 4849 m above sea level. There are a few modern glaciers in the mountain peak above 4500 meters. The northwest part of the mountain is higher, which is the main part of Tuolai mountain. The southeast part is lower, which is called Moeller mountain, also known as EBO mountain.

Tuolai Nanshan, also known as basola mountain, also has the names of Taolai Nanshan, Tuole Nanshan and Taolai Nanshan. Tuolai south mountain is located between Shule River and Tuolai River, which is divided by Shule River and Daxueshan in the northwest, and the upper reaches of Sala River and moele mountain in the southeast. The west section is the boundary mountain of Qinghai and Gansu provinces, and the east section is all in Qinghai Province. In Qinghai Province, it is 200 km long and 20-25 km wide. The mountain peaks are generally between 4500-5000 m above sea level. The highest peak is wudeeqin, with an altitude of 5294 M. the peaks above 4500 m generally have modern glaciers.

South Shule mountain is located in the south of Shule River and the north of Dang River and Hala lake.

In Qinghai Province, it stretches for 350 km and is 30-50 km wide. The mountain peaks are generally 4500-5500 m above sea level. The western section of Shule Nanshan is called YEMA Nanshan in Gansu Province, and the middle and eastern sections are in Qinghai Province. The highest part of the middle section is also the highest part of the Qilian Mountains uplift. The mountains above 5000 meters are widely distributed. There are three peaks above 5500 meters. The highest peak is gangze, once known as Tuanjie peak, with an altitude of 5808 meters. The eastern section is called shaguolinnamujimuling. Modern glaciers are well developed in the middle and eastern sections, and there are eight large snow mountains.
