摘　　要：为满足水土保持规划设计对数据高精度、高效率及现势性要求,并探究低空遥感技术在水土保持规划设计中的应用前景,本研究以榆林市横山区鲍家寺景区为研究区,基于数字正射影像(DOM)和数字高程模型(DEM)构建三维模型和矢量图。结果表明:与公开获取的遥感数据在时效性、分辨率和精度方面进行对比分析发现,公开获取的实验区遥感影像偏移量中误差约为1.75 mm,低空遥感获取的实验区影像偏移量中误差约为0.47 mm,低空遥感影像较谷歌等可公开获取的影像精度更高、分辨率更好、时效性更强。In order to meet the requirements of high precision,high efficiency,and timeliness in soil and water conservation planning and design,and to explore the prospects of applying low altitude remote sensing technology to soil and water conservation planning and design,this study took Baojiasi Scenic Area of Hengshan District,Yulin City as the experimental area,based on digital orthophoto model(DOM)and digital elevation model(DEM),three-dimensional terrain simulation and vectorization data were carried out.The results showed that compared with publicly available remote sensing data in terms of timeliness,resolution,and accuracy,the remote sensing images of publicly available experimental area had a mean square error of about 1.75 mm in offset,and the low altitude remote sensing images had a mean square error of about 0.47mm in offset.Low altitude remote sensing images have higher accuracy,better resolution,and stronger timeliness compared to publicly available images such as Google.
