摘　　要：在河道整治工程中,传统方法对区域性水土流失的监测准确率偏低。提出河道整治区域水土流失监测与水土保持方法,分别提取降雨侵蚀力因子、植被覆盖因子、坡度因子、土壤可蚀性因子及生物措施因子,在划分水土流失强度等级标准后,通过对水土流失因子的叠加计算,得到水土平均流失厚度,从而确定水土流失级别。通过对比结果发现,该方法能够准确监测水土流失强度等级。In river regulation projects, the accuracy of traditional methods in monitoring regional water and soil loss is low.Therefore, the methods of regional soil and water loss monitoring and soil and water conservation in river training projects are proposed. Firstly, rainfall erosivity factor, vegetation coverage factor, slope factor, soil erodibility factor and biological measure factor are extracted respectively. Then, after dividing the level standard of water and soil loss intensity, the average thickness of water and soil loss is obtained through the superposition calculation of water and soil loss factors, so as to determine the level of water and soil loss. The comparison results show that the method can accurately monitor the intensity grade of water and soil loss.
