The Great Xing'an Mountains are the western component of the Xing'an Mountains, located in the northwest of Heilongjiang Province and the northeast of the Inner Mongolia Autonomous Region, and are the watershed of the Inner Mongolia Plateau and the Songliao Plain, connecting with the Taihang Mountains and the Xuefeng Mountains to form a line, connecting Inner Mongolia, Heilongjiang, Jilin, Liaoning and other places.

Schematic diagram of the Great Khing'an Mountains.
The Great Khing'an Mountains are not actually steep, but gentle.
The total area of the Daxing'an Mountains is about 327,200 square kilometers (including about 240,000 square kilometers in the Inner Mongolia Autonomous Region and 84,800 square kilometers in Heilongjiang Province)
Green mountain forests

The Great Khing'an Mountains start from the bank of the Heilongjiang River (northeast backbone) in the north, reach the upper valley of the Xilamulun River in the south, northeast - southwest direction, with a total length of more than 1400 kilometers, a width of 200~400 kilometers, an altitude of 1100~1400 meters, and the main peak is Suoyueerji Mountain.
A family in the woods
The Daxing'an Mountains not only support the lifeblood of industry, agriculture, animal husbandry and fishery in Northeast China and Inner Mongolia, but also serve as the granary and source of drinking water to sustain life.

The forest ecosystem of the Daxing'an Mountains is a natural green barrier between the Songnen Plain and the Hulunbuir Grassland, and is one of the important forestry bases in China.

The topography of the Great Khing'an Mountains is high in the west and low in the east, located at the eastern edge of the second ladder of the terrain, the junction of the second and third echelons, the east of the ridge of the Great Khing'an Mountains is the third terrace, and the west is the second terrace, which belongs to the shallow hilly area.
There are also large flatlands in the woods.
The northern, western and central parts of the Great Khing'an Mountains are high. The average altitude is 573 meters, the highest peak is Huanggangliang (2029 meters above sea level), and the lowest altitude is 180 meters (Yanjiang Village, Sanka Township, Huma County). The winter is cold and the summer is warm, the temperature difference between day and night is large, the annual average temperature is minus 2.8 °C, the lowest temperature is minus 52.3 °C, the frost-free period is 90~110 days, and the average annual precipitation is 746 mm, which belongs to the cold temperate continental monsoon climate.
The Great Xing'an Mountains are bounded by the Taoer River in the territory of the Xing'an League, and are divided into two sections, north and south. The northern section is about 770 kilometers long, the terrain gradually rises from north to south, and the second peak is located in the Arshan Ferris Ridge of Xing'an League, with an altitude of 1711.8 meters. The east and west sides of the mountain are the tributaries of the right bank of the Nenjiang River and the birthplace of the water system of the Ergun River, with a forest cover rate of more than 60%, mainly coniferous forests dominated by the Larix gmelinii of Xing'an, and the main tree species are Larix gmelinii sylvestris, Pinus sylvestris, Picea koraiensis, Birch, Quercus mongolica, Aspen, etc., which are important ecological barriers and national forest conservation areas in Northeast China.

The southern section, also known as Sukexilu Mountain, is about 600 kilometers long and has mostly grassland vegetation. In the east of the Daban-Lindong-Lubei-Ulan Hada line, the low mountain area has a gentle slope and wide valleys, and the wide mountain basins are interlaced with the river valley plains, which is an excellent grass pasture.
Huanggangliang is the highest peak of the Great Xing'an Mountains, with an altitude of 2029 meters, located in the northeast of Keshiketeng Banner in Inner Mongolia, the Huanggangliang area has preserved the most complete form of the Quaternary glacier, and the types are diverse, it is a typical valley glacier, there are glacier relics such as cirque, U-shaped valley, horn peak, terminal moraine embankment, side moraine embankment, streak stone drift gravel on both sides of Huanggangliang, which is called the ice valley forest sea, it is the Quaternary glacial relics found with the best preservation, complete glacial landform and the highest scientific research value.
Major mountain ranges
In 2020, the Hulunbuir Civil Affairs Bureau named 14 branches and sub-branches of the Daxinganling Mountains in the administrative area of Hulunbuir City. The names are as follows: Wuhe Mountain Branch, Sanqi Mountain Branch, Yalada Baula Branch, Wuzhigen Ula Branch, Duolun Mountain Branch, Mokeling Branch, Gaoping Mountain Branch, Yilkuri Mountain Branch, Gannuo Mountain Branch, Gardun Mountain Branch, Yacshan Branch, Alazi Mountain Branch, Zakchi Mountain Branch, Hueryatai Mountain Branch.
Green as a blanket.
The main watershed between the Heilongjiang River and the main vein of the Daxing'an Mountains in the south is the Emur Mountains, with an average altitude of about 1,000 meters, constituting the eastern middle mountain zone; the Huoluotai Mountain between the Laochao River and the Dalin River, with an altitude of 927 meters above sea level, and the terrain is slightly lower, constituting the middle mountain zone in the north-south direction; and the west is the main vein at the northern end of the Daxing'an Mountains, with an altitude of more than 1,000 meters above sea level, and the terrain is higher to form the middle mountain zone in the north-south to the west.

Haraha volcanic group
Located in Arshan, the Halaha Volcanic Group is one of the important volcanic groups in the Greater Khing'an Mountains, with an area of 3,500 square kilometers, ranking first in Asia and second in the world. Among them, there are more than 50 volcanic cones, hundreds of volcanic mounds, 7 high-level crater lakes (Tianchi), dozens of lava dam lakes, and the more famous ones are Songye Lake, Rhododendron Lake, Wusu Langzi Lake, Luming Lake and various lava landforms. The lava mounds in the Daheigou area are the largest basalt landforms in China.

biological resources
There are more than 40 kinds of exotic beasts such as reindeer, moose, snow hare, sable, flower-tailed hazel pheasant (also known as flying dragon) and so on in the Daxing'an Mountains, and the energy flow and material circulation of the forest itself maintain and optimize the ecological environment of the Daxing'an Mountains.
