黄土高原是我国也是世界上水土流失最严重的地区。由于黄土母质具有易遭侵蚀的特点，加上不合理的农耕制度和地表缺少植被覆盖等因素，降水携带着大量表层土壤从黄土坡上冲蚀，并以每年剥蚀1～2cm厚度的速度进行着。每年输入黄河的泥沙量达16亿吨之多，严重影响当地和黄河下游
The Loess Plateau is the most serious area of soil and water loss in our country and in the world. Due to the characteristics of loess parent material being easily eroded, coupled with unreasonable farming systems and lack of vegetation cover on the surface, precipitation carries a large amount of surface soil erosion from the loess slope and is carried out at a speed of 1 ~ 2 cm per year . Each year the amount of sediment input into the Yellow River reaches 1.6 billion tons, seriously affecting the local area and the lower reaches of the Yellow River
