| Abstract: | The reasons why the soil erosion and water loss in Pisha sandstone are serious are analyzed.By using model of universal soil loss equation and analog method,the amount of soil erosion and water loss of Da-Dong Highway which is constructed in Pisha sandstone area is predicted.According to the consequence of prediction,the characteristics of soil erosion and water loss and the principle of soil and water conservation of highway construction project in Pisha sandstone area are presented. |
