When is the best time to go to Ergon River?

The Best Time in Ergon: Spring and Summer.

Ergon River is a tributary of Heilongjiang, and its upstream is the Krulun River, which originated in Mongolia. Since the signing of the Sino-Russian Nebuchadnezzar Chu Treaty in 1689, it has been the boundary river between China and Russia. The main tributary is Hailar River. With Hailar River as the source, the total length is1620km.

It is called Wang Jianhe in the Book of Old Tang Dynasty, Ergon River in the Secret History of Mongolia, Yeluguna River in the Yuan Dynasty, Arunalian River in the Ming Dynasty and Ergon River since the Qing Dynasty.

The topography of the upper and lower reaches of Ergon is quite different. Abagaidui to Heishantou is a grassland hilly area with flat terrain, wide river valley, numerous lakes and swamps, scattered water flow, overgrown weeds and wicker. Since the right bank of Genhe River, Delbe River and Hall River entered, the water volume has greatly increased. From crude charts to the Gilalin River, the valley becomes narrow, there are more sandbars and islands in the river, and the river becomes deeper. From below Jilalin, the river enters the canyon, the valley is narrow, the mountains on both sides are steep, the riverbed is stable and the water flow is stable. The river is about 200 and 300 meters wide and the water depth is more than 2.5 meters. This is a good waterway and rich hydropower resources.

The areas along the Ergon River are rich in fertile land, dense forests, abundant aquatic plants, various fish species and abundant animal and plant resources, which are suitable for farming and grazing. It is an ideal paradise for human beings.

The good natural environment here has bred many ancient ethnic minorities. Ancient Mongolian tribes once roamed, fished and hunted here, and were deeply proud of this beautiful home. Later, Genghis Khan left his younger brother, Hasal, here, and there are still relics of his palace in Heishantou.

The Ergon River is 970 kilometers long. Compared with other river mothers in the world, she is still a little mother. Its total drainage area is 6.5438+0.5 million square kilometers, which is equivalent to the area of four Taiwan Province provinces. There are more than 800 rivers along the way, such as Hailar River and Genhe River/kloc-0. With so many rivers, can grasslands be good? Its water system also includes Hulun Lake, Haraha River, Ursong River and Krulun River (now Mongolia, its downstream flows into Hulun Lake).
