The weather in Yuanyangtou, Fujian

Is the source of Yongjiang River in Guangxi huge now? Yuanyang pot? Fairyland, soil erosion may have some impact on the geographical environment. First of all, soil erosion will lead to the decline of land productivity and poor soil. Secondly, soil erosion will lead to water pollution, reservoir siltation and some floods. In addition, soil erosion will also cause land desertification, leading to the deterioration of the natural ecological environment. ?

Recently, a rare phenomenon has appeared in Sanjiangkou, Jiangnan District, Nanning. Yuanyang River? Landscape, the color of the river is green on one side and yellow on the other, which is very beautiful. But the beauty brought by this kind of soil erosion is not what most people want to see, and soil erosion will have a certain impact on the geographical environment.

First of all, soil erosion will cause the decline of land productivity and poor soil. Soil erosion will lead to the loss of many nutrients in the soil, such as nitrogen, phosphorus, potassium and so on. You will reduce the content of some trace elements, such as manganese, iron and so on. The loss of trace elements in cultivated land will reduce by one third or even one half, which will seriously affect the yield of crops.

Secondly, soil erosion will lead to water pollution, reservoir siltation and some floods. Because of soil erosion, a large amount of sediment enters the river, which may block the river and then accumulate in the reservoir, which will affect some water conservancy projects and water quality. Most importantly, because rivers are blocked, floods may occur, which may eventually affect people's lives and agricultural production and bring about a series of ecological imbalances.

In addition, soil erosion will also cause land desertification, leading to the deterioration of the natural ecological environment. Fertile sandy land is a foundation of desertification, and a large amount of sediment will be carried in the process of soil erosion. If the river dries up, only the sediment is left, and the sediment moves naturally, then this kind of desertification may occur, and even sandstorms may occur. Therefore, soil erosion is related to desertification.

These are some of my related views.
