摘　　要：水土流失背景值在水土保持工作中应用广泛,但受地域差异、时空变化以及影响因子复杂等影响,一直难以精确测算。水土流失监测和遥感技术的不断完善以及水土保持数字化工作的深入推进,使得精准量化水土流失背景值的条件日趋成熟。研究梳理了水土流失背景值取值存在的主要问题,分析了7种水土流失背景值的测算方法及其应用情况。结合工程案例应用效果,提出“七因子”法为适合安徽省水土流失背景值的测算方法。The background value of soil and water loss is widely applied in soil and water conservation efforts.However,due to factors such as regional differences,spatiotemporal variations,and the complexity of influencing factors,it has been difficult to calculate accurately.With the continuous improvement of soil and water loss monitoring,remote sensing technologies,and the deepening of digital soil and water conservation efforts,the conditions for accurately quantifying the background value of soil and water loss have gradually matured.This study reviews the main issues associated with determining the background value of soil and water loss and analyzes seven methods for calculating the background value of soil and water loss and their applications.Based on the effectiveness of these methods in engineering cases,the study proposes the "Seven Factors" method as a suitable approach for calculating the background value of soil and water loss in Anhui Province.
