1. The Pearl River, also known as the Yuejiang River, is the second largest river in China? , the third longest river in China. The Pearl River originally refers to a 96-kilometer-long waterway from Guangzhou to the estuary, which is named after it flows through the famous Haizhu Island (Stone). Later, it gradually became the general name of Xijiang, Dongjiang, Beijiang and Pearl River Delta rivers? .
2. Heilongjiang used to be the inland river of China, the third largest river after the Yangtze River and the Yellow River. During the Qing Dynasty, Russia forced the Qing government to sign the unequal Sino-Russian Love-fainting Treaty and the Beijing Treaty, and the middle and upper reaches were designated as the Sino-Russian border river.
Hydrological characteristics of the Yangtze River
The total water resources of the Yangtze River is 96 16 billion cubic meters, accounting for about 36% of the total river runoff in China and 20 times that of the Yellow River. The Amazon River and the Congo River (Zaire River) are second only to the equatorial rainforest, ranking third in the world.
The parana river-La Plata River in South America and the Mississippi River in North America, which are similar in latitude to the Yangtze River basin, have a basin area larger than that of the Yangtze River, but their water consumption is far less than that of the Yangtze River. The former accounts for about 70% of the Yangtze River, while the latter accounts for about 60% of the Yangtze River.
Due to the large population in the basin, the per capita water consumption is 2760 cubic meters, which is only 1/4 of the world's per capita water consumption. The characteristics of water resources in the Yangtze River are mainly reflected in the temporal and spatial distribution of river runoff, and the surface water resources in the basin account for 99% of the total water resources. In surface water resources, river runoff accounts for more than 96%.
