Jinghe River and Weihe River are the main rivers in the Yellow River Basin, which mainly flow through Shaanxi. Weihe River is the largest tributary of the Yellow River, and Jinghe River is the largest tributary of Weihe River. When Jinghe River and Weihe River meet in Gaoling District, Xi City, due to the different sediment concentrations of the two rivers, they present a strange landscape where clear water and turbid water meet and one river is incompatible, forming a distinct scene.
Extended data
The turbidity of water mirror and Wei water is different, and the turbidity of water mirror and Wei water has changed from water mirror turbidity to Wei water turbidity.
1. The ancients thought that the Jing water was turbid and the Wei water was clear, which can be verified in the poems of Du Fu, a poet in the Tang Dynasty, and can also be verified from a geographical perspective. Judging from the area it flows through, the Weihe River flows into Shaanxi from Gansu Bird and Mouse Mountain, joins the Yellow River, and flows through Guanzhong Plain and Qinchuan for 800 miles. Water mirror flows through the Loess Plateau, which is an area with serious soil erosion. As far as the sediment concentration of the river is concerned, it should be that the water mirror is greater than the Weihe River.
2. But in today's society, where the two rivers meet, the Weihe River is turbid in the Shuijing River. The reason is the influence of the environment. Human activities in the upper reaches of Weihe River have caused serious environmental damage and serious soil erosion. Moreover, the characteristics of soil mineral composition in the area where the Weihe River flows make the water color red and yellow when the sediment concentration of the Weihe River reaches 10kg/m3. So the color of Wei River is deeper than that of Jing River.
