摘　　要：随着测量技术的不断发展,无人机在水土保持监测、监督方面的应用日益广泛。为更加高效、科学地制订航飞计划,通过设置不同航高、航向/旁向重叠度,总结了无人机航片相幅面积、分辨率的变化规律,分析了航高和重叠度对相幅面积的影响。图幅面积、地面分辨率均与航高之间存在极显著的正相关关系,航高、航向/旁向重叠度的变化会对图幅面积产生影响,在一定升限内图幅面积对航向重叠度的变化更为敏感。通过设置最优参数,利用无人机科学高效地完成了青海省国家水土保持重点工程信息化监管工作。As the continuous development of measurement technology,the application of unmanned aerial vehicle(UAV)is increasingly widespread to the monitoring and supervision of soil and water conservation.In order to make a more efficient and scientific flight plan,it summarized the changing law of mapping area and resolution and analyzed the influence of altitude and overlap to mapping area through setting different altitude,course/wayside overlap.There are significant positive correlation between map area,ground resolution and altitude.The change of altitude and course/wayside overlap would affect the mapping area and the map area is more sensitive to the change of course overlap within a certain lift limit.The informatization supervision of national key projects of soil and water conservation in Qinghai had been completed efficiently with UVA by setting the optimal parameters.
