- Abstract
The highway project in mountainous area will lead to serious soil erosion,due to its long road line and large volume of the work.While the program of water and soil conservation is drawn up,the prediction of the amount of soil erosion is needed. The whole amount of soil erosion comprises primary and new soil erosion amount. The primary soil erosion amount may be predicted by the method of average erosion modulus or universal soil loss equation.The new soil erosion amount is made up of erosion amount due to disturbed earth surface and discarded soil.Finally, the prediction model of soil erosion amount about a specific highway project during its construction period in mountainous area is analyzed.
