摘　　要：为了能够充分了解土壤侵蚀分布,及时掌握水土流失变化趋势,提出基于无人机倾斜摄影遥感技术的水土保持动态监测方法。利用无人机从多个角度采集监测区域影像数据,并实施辐射定标和大气校正预处理,基于遥感影像数据提取土壤可蚀性因子、土地利用因子、植被覆盖监测因子、坡度因子,通过计算获取水土保持系数并划分等级。监测结果表明:区域1水土保持系数呈现“V字形”,区域2水土保持系数整体呈现“一字型”,区域3水土保持系数整体呈现逐渐上升状态。In order to fully understand the distribution of soil erosion and grasp the changing trend of soil erosion in time,this study proposes a dynamic monitoring method of soil and water conservation based on UAV tilt photography remote sensing technology.It uses unmanned aerial vehicle(UAV)to collect the image data of monitoring area from multiple angles.The radiation calibration and atmospheric correction pretreatment is conducted based on remote sensing image data,soil erodibility factor,land use factor,vegetation coverage monitoring factor and slope factor are extracted,and soil and water conservation coefficient is obtained through calculation and graded.The monitoring results show that the soil and water conservation coefficient in area 1 is V-shaped,the soil and water conservation coefficient in area 2 is straight,and the soil and water conservation coefficient in area 3 is gradually increasing.
