All life on earth is inseparable from water, and water is the origin of all life. There are many rivers in China, and the Yangtze River and the Yellow River are the origins of Chinese culture. Do you know where Qitaihe culture originated? That’s right, it’s the Wusuli River. Let’s take a look inside Qitaihe culture.
The Ussuri River is a major tributary on the right bank of the Heilongjiang River and an important boundary river on the Russian border in northeastern China. The Wusuli River has a total length of 880 kilometers and a drainage area of ??nearly 190,000 square kilometers, covering 61,500 square kilometers in Heilongjiang Province, China. The Wusuli River is rich in salmon, soft-shell turtle, etc. The middle and lower reaches can navigate ships of 300 to 1,000 tons.
The Ussuri River Basin has relatively high precipitation. There are 174 large and small tributaries along the way. The larger tributaries on the Chinese side include the Muling River, Naoli River, etc., running across it and east of it. The main stream of Wusuli River is on one side and the Fuyuan Waterway is on the west.
The Ussuri River has two sources, the east and the west. The east source, the Ural River, originates from the west side of the Sikhote Mountains in Russia. The Ural River is 398 kilometers long in Russia. The Songacha River in Xiyuan originates from Xingkai Lake. After the two rivers merge, they flow from south to north through Mishan, Hulin, Raohe, Fuyuan and other counties, to the northeast corner of the Fuyuan Delta, and flow into Heilongjiang from the right bank.
The width of the Wusuli River is 200-500 meters from the mouth of the Songacha River to the Rao River, and 500-1000 meters from the mouth of the Rao River to the Heilongjiang River. The average water depth of normal water level is 2-5 meters. The multi-year average freezing time is 148 days, and the maximum ice thickness is 1.15 meters. The multi-year average runoff at the downstream Raohe Station is 23.29 billion cubic meters, and the multi-year average runoff at the river mouth is 62.35 billion cubic meters. The main tributaries in China include Muling River, Qihulin River, Abuqin River and Naoli River.
The entire Ussuri River runs through the vast longitudinal valley between the Wanda Mountains in China and the Sikhote Mountains in Russia. Its upper reaches are formed by the confluence of the Wula River and the Daobi River. It flows on the eastern edge of the low-level Hulin Basin, flows northeast to the Khabarovsk area, turns sharply to the southwest, and flows into the Heilongjiang River. The terrain above the confluence of the Songaca River is higher and the valley bottom is flat.
Below the confluence is a gentle longitudinal valley with a width of 300 kilometers. The terrain is low-lying and gentle, the ground is strongly swampy, and the water flow is slow. Many river sections form meandering or network waterways, forming a famous primitive wetland. landscape. There is a section of the river in the middle reaches of Raohe County, with low hills and mountains approaching the river on both sides.
Jiangdong originates from the western foothills of the Sikhote Mountains in eastern Russia, flows from south to north, originates from the Songaca River in the west, and originates in the northeast of Xingkai Lake, which is the only outlet of the lake.
From a geomorphological point of view, the Chinese side of the Wusuli River Basin can be divided into three parts: the upper reaches is the Xingkai Lake Plain; the middle part is the Wanda Mountain area; and the lower reaches is the Sanjiang Plain. The river basin is criss-crossed by rivers, dotted with lakes, islands are like a string of pearls, and are interspersed with forests, grasslands, swamps, wetlands, plains, mountains, rivers, waters and land. The natural vegetation on both sides of the bank is kept intact, with dense trees and abundant aquatic plants. Roam along the river. The natural scenery of the Wusuli River is something you can't find anywhere in the rivers in mainland China.
The Wusuli River is one of the few unpolluted rivers in China. Here you can see the Danhadaling Forest and Sanjiang Plain on the west bank of the Yangtze River. The east bank of the river is full of mountains and steep cliffs.
