坡面侵蚀是水土流失的源区 ,有必要加快坡面水土治理。由于坡面降雨入渗、汇流、产沙输移实质上是一种逾渗过程 ,则可用逾渗理论指导坡面耕地和非耕地的水保措施。通过比较多种二维点渗流 (雨水占据坡面格点 )逾渗模型的逾渗阈值 ,从理论上认为按蜂房形对坡面进行水利及生物工程治理水土流失具有较好的效果 ,为水保措施指引了一条新的思路。
Slope erosion is the source area of soil and water loss, it is necessary to speed up water and soil erosion control. Because of rainfall infiltration, confluence and sediment transport on slope, the percolation process is essentially a percolation process. Percolation theory can be used to guide soil conservation measures on arable land and non-cultivated land. By comparing the percolation thresholds of percolation models with many two-dimensional seepage seepage points (rainwater occupies the slope grid points), it is theoretically considered that it is effective to control water and soil erosion by water and bioengineering according to the apiary shape, Insurance measures guide a new way of thinking.
