| 摘 要： | 通过在青海省共和盆地多次野外调查的基础上,以威连滩冲沟沟头的南支沟为研究案例,采用三维激光扫描仪和亚米级的差分GPS分别对该支沟进行了侵蚀边界的监测,利用点云处理软件Real works Survey,AutoCAD和GIS软件对2种测量数据进行了处理计算和对比分析.结果表明,三维激光扫描仪在土壤侵蚀监测中非接触的高精度测量,可以真实反映地表形态;对于扫描仪没有扫描到的黑洞数据,高精度的差分GPS可作为一个局部的数据补充,并探讨了三维激光扫描技术在土壤侵蚀研究应用中的缺陷及其改进,旨在为水土流失监测提供一种新的思路和方法.

| Abstract: | Based on several traditional field investigations in Gonghe basin,Qinghai Province,laser 3D scanner and sub-meter differential GPS were used to monitor the boundary of branch gully erosion in the south of Weiliantan gully head. After the data were collected,point-cloud data processing software-Real Works Survey,AutoCAD,and GIS software were used to compare and analyze the raw data. Results showed that high precision and non-contact measurement of laser 3D scanner could accurately simulate landform surface in soil erosion monitoring. High precision GPS data can be used as part of supplement data in the area where laser 3D scanner can not reach. Moreover,the limitations and improvements of laser 3D scan technology applied in soil erosion research were discussed. Our study is expected to provide a feasible method in the research on soil erosion monitoring. |
