Main stream situation

Ermur river is also known as "ermur River", formerly known as abaxi river. In 1980, the name of the river was changed to Xing'an river. For convenience of description, modern hydrology is still known as ermur river. It is a tributary on the right bank of the upper reaches of Heilongjiang Province. It originates from the pheasant farm mountain on the north side of Daxing'an Mountains. From south to north, it gathers the tributaries of Laocao River (Laochao River), Dalin River, Gulian River and so on, crosses the whole territory of Mohe City, and flows into Heilongjiang near Dahexi village of Xing'an township. It has a total length of 469 km, a river width of 20-150 m, a water depth of 2-5 m and a drainage area of 16280 square km. It is the second largest tributary in the upper reaches of Heilongjiang Province, and the length and drainage area of the main stream are second only to Huma River.

The river has three streams, the Amur River in the East, with a total length of 469 km and a main stream of 360 km, including 230 km of the main stream of the ermur River, Laochao River in the South and Dalin River in the West. Most ancient books regard this source as the main source of the ermur river. Three sources into the eastern town of Xilinji County, known as the e Muer river. In modern hydrology, Amur River is the main source of ermur river.

Amur reach

The total length of the ermur River from the Dalin estuary to the estuary is 230 km. Mountains stand on both sides of the river bed, and the river course is winding with many serpentine curves. The river flows around the mountain, seven turns and eight turns. Many Oxbow lakes and sandbank plains were formed. The bending distance of the river is 10 times of the straight distance, and it is the main channel for transporting timber in the territory.

Main tributaries

Tributaries of Amur River

Chilima River, both big and small, originate from the southern end of the construction area of the struggle forest farm, starting from forest class 117 and forest class 103 respectively. The two rivers flow about 10km northward, converge at 1km to the south of the forest farm, and then flow into Amur River in the east of the forest farm.
