with the development of information technology, land reclamation needs more tools to meet the demand of planning and design. 3D laser scanning technique potentially provides a novel tool for generating an accurate and comprehensive 3D mathematical description of environment in mining area, which can help study and analysis the problems in land reclamation. The developments of 3D laser scanning technique were introduced in this paper, and then several main application aspects for land reclamation were put forth. The application of 3D laser scanning technique in land reclamation can enhance the work efficiency and be a useful tool for land reclamation.
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 checkerboard barriers were simulated. And the state of erosion and deposition was scanned. It is concluded that the state of erosion and deposition, 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.
