中文摘要	三维激光扫描技术是近年来发展起来的新型空间信息测量技术.本文将三维激光扫描技术引入治沙工程领域,通过实验对草方格沙障内的蚀积微形态变化过程进行了模拟,并应用三维激光扫描仪测定草方格沙障内蚀积变化状态,认为草方格沙障内的蚀积状态,蚀积深度以及由堆积转化为侵蚀的位置等由于坡度等条件的不同而有所差异,从而证明了应用三维激光扫描技术监测微地貌形态变化过程的可行性.同时认为该技术在沙丘移动监测、机械沙障合理设计及防沙治沙效益评估等方面具有独特的优势和广泛的应用前景.但其技术本身和应用方面仍有一些问题亟待解决.
英文摘要	3D laser scanning technique is a technology for spatial information collection, which has been developed in recent years. We introduce the 3D laser scanning technique into desert control engineering. Micro-relief changing processes in straw checker-board barriers were simulated. And the state of erosion and deposition was scanned. It is concluded that the state of erosion and deposi-tion, the erosion depth and the position where deposition is replaced by erosion in straw checkerboard barriers are different because of different slopes and other conditions, and the application of 3D laser scanning technique in micro-relief dynamic processes simulating is proved to be feasible. The preliminary results also show that 3D laser scanning technique has unique superiority and broad application foreground in monitoring sand dunes movement, designing mechanical sand barriers, and benefit assessment of desert control measures. But some problems still exist in technology and application and need to be solved immediately.
