Process Of Heavy Rain Water Scouring The Soil Which Is Loose, Porous And Has Vertical Fissures !

Показать описание

The soil erosion on the Loess Plateau is a serious ecological problem !

Its main causes include natural factors and human factors. In terms of nature, the soil on the Loess Plateau is loose, with many pores and vertical fissures, and is vulnerable to erosion. The precipitation is concentrated and there are many rainstorms, which have a strong scouring force on the soil. Among the human factors, unreasonable human activities such as excessive reclamation, overgrazing, and deforestation have damaged the surface vegetation, causing the soil to lose protection and exacerbating soil erosion !

Soil erosion has brought many harms, such as the decline of soil fertility, the reduction of cultivated land, and the decrease of crop yields; the increase of sediment content in rivers, the siltation of river channels and reservoirs, the reduction of the regulation and storage function and shipping capacity of water conservancy facilities; the deterioration of the ecological environment, affecting the production and life of local residents, etc.

In order to control the soil erosion on the Loess Plateau, a series of measures have been taken, such as planting trees and grass, returning farmland to forests and grasslands, building terraces, and building dams and silt storage areas, to increase vegetation coverage, reduce soil erosion, and gradually improve the ecological environment !
