摘　　要：以兰州市城关区伏龙坪和红山根为典型滑坡研究区，通过配准、取样及点云数据可视化分析，分别得到两处典型滑坡的变形结果：2014．08．27—2014．09．27伏龙坪研究区位移变形集中在-0．274-0．154m，红山根研究区的集中在-0．170-0．132m；2014—09—27—2014—11—12伏龙坪研究区位移变形集中在-0．493-0．155m．实践说明3维激光扫描仪和GIS在滑坡监测分析方面的应用，可以为滑坡危险性评价提供较为科学的依据．Fulongping and Hongshangen in the Chengguan District of Lanzhou were selected as typical study areas, Through registration, sampling and point cloud data visualization and analysis, two typical landslide deformation results were produced respectively： the displacement and deformation of ~longping was focused from -0.274 m to 0.154 m and that of Hongshangen was concentrated from -0.170 m to 0.132 m during 2014-08-27 to 2014-09-27; the displacement and deformation of Fulongping was focused from -0.493 m to 0.155 m during 2014-09-27 to 2014-11-12. Thus the experiment showed that the application of 3D laser scanner and GIS in landslide monitoring analysis can provide us with more scientific evidence for landslide hazard assessment.
