基于侵蚀模数法的道路水土流失预测与防治

Prediction and Prevention of Road Soil and Water Loss Based on Erosion Modulus Method

随着经济的快速发展和城市化进程的加快,人为因素已经成为水土流失的主导因素,东莞市大岭山镇矮岭冚村地块配套道路工程建设期间降低了植被覆盖率,破坏原有生态防护体系,开工后将造成不同程度的水土流失,亟需防护治理。在分析该工程区域水土流失现状及影响因素的基础上,进行水土流失预测,并划分两个水土流失防治分区。采取工程与植物措施相结合的综合防治措施,以期使因工程建设而引起的水土流失降到最低程度,并进行水土保持监测布置和效益评价分析,结果显示防治指标均达到目标值,效益良好。

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.
