"The Great Wall of the Yangtze River, huangshan, and the Yellow River weigh thousands of pounds in my heart", this is the famous singer Zhang Mingmin once sang "My Chinese Heart" at the Spring Festival Gala in 1984. As soon as the song was sung, it spread all over the country and became a must-do song for almost every Chinese. The Yangtze River and the Yellow River are one of the long rivers in China, they have witnessed the origin and development of the Chinese nation, and have nurtured generations of Chinese people. However, there is a river in China that has seven times the total water resources of the Yellow River and is larger than the Yangtze River, but it is little known.
"Heilongjiang" is not only the name of a Chinese province, but also the name of a large river, which flows through Mongolia, China, russia, and is a famous river in Asia. In the early years of the Qing Dynasty, Heilongjiang was called "Sakhalian Ula" in Manchu, "Sakhalian" means "black", and "Ula" means "River". The reason why Heilongjiang is called Heilongjiang is because its water quality contains more humus and the water quality is black, so it is also called "black water" and "weak water" in ancient China.
Since the liao dynasty, Heishui has been officially called "Heilongjiang", according to the "LiaoShi Daozong Benji": Taikang three years of spring and the first moon of the ugly, such as the Mixed River (that is, Songhua River). Summer april, rafting in Heilongjiang. In the years that followed, people thought that the water of Heilongjiang was black, like a dragon, so it was called "black dragon". Heilongjiang has two sources, north and south, starting from the Hailar River, with a total length of 4,440 kilometers and a basin area of 1.856 million square kilometers, which is larger than the 1.8 million square kilometers of the Yangtze River.
The Heilongjiang River was originally an inland river in China, the third largest river after the Yangtze and Yellow Rivers. However, in the Qing Dynasty, the Qing court was cowardly and weak, and under the persecution of Tsarist Russia, it signed an unequal treaty, the Sino-Russian Treaty of Yaohun and the Treaty of Beijing. In the treaty, Tsarist Russia forcibly divided the upper and middle reaches of the Heilongjiang River into the boundary rivers between China and Russia. In addition, the Heilongjiang River system is the most extensive water system in the East Asian river basin, flowing to the southeast and then turning to the northeast, receiving the two major tributaries of the Songhua River and the Ussuri River on the way, and finally entering the sea in Russia. The so-called "Three Rivers Plain" is derived from the names of the three major rivers of Heilongjiang, Songhua and Ussuri.
Compared with the total water resources of the Yellow River, Heilongjiang can be said to have an advantage, as we all know, the Yellow River is the birthplace of Chinese culture, Chinese affectionately call it "Mother River". However, because the middle section of the Yellow River flows through the Loess Plateau region, it will wash away a large amount of sediment on both sides, about 1.6 billion tons per year, and is known as the largest river in the world with the largest sediment content. As a result, the average annual flow of the Yellow River is only 58 billion cubic meters, while the Heilongjiang River has 346.5 billion cubic meters, which is six times that of the Yellow River.
There is a saying in China called "big waves and sand", which is suitable for Heilongjiang. According to historical records, the area along the Heilongjiang River was once rich in placer gold, so that the people living here gradually became rich, until it was uniformly controlled by the imperial court, and the annual production of placer gold in the Heilongjiang River Basin made the princes and nobles extremely excited.
There are many alluvial islands on the main stream of the Heilongjiang River, including Gucheng Island, Oupu Old Street Base Island, Fuyuan Delta and so on. One of the most famous islands is the Fuyuan Delta, also known as the "Black Blind Island", which is a closed island surrounded by water on three sides and represents the friendship between China and Russia.
