Abstract
With the rapid development of economy and the acceleration of urbanization process,human factors have become the dominant factor of soil and water loss.During the construction of the supporting road project in Ailing Ham Village,Dalingshan Town,Dongguan City,the vegetation coverage rate has been reduced,which destroys the original ecological protection system,and will cause soil and water loss in different degrees after construction,which needs urgent protection and control.Based on the analysis of the current situation and influencing factors of soil and water loss in the project area,this paper makes a prediction of soil and water loss,and divides two soil and water loss prevention zones.In order to minimize the soil and water loss caused by engineering construction,the soil and water conservation monitoring arrangement and benefit evaluation analysis were carried out.The results showed that the control indexes reached the target value and the benefits were good.关键词
