| 摘 要： | 为了提高开发建设项目水土保持监测中侵蚀强度测量的效率和精度,尝试使用3D激光扫描仪对排土场堆弃土边坡进行土壤流失量监测,并与常用的测钎法进行比较。结果表明:在同一水土流失坡面同时期的监测中,传统测钎法的监测结果与3D激光扫描法监测的结果偏差为13.26%;3D激光扫描仪具有较高的土壤形态变化记录性能,相对传统的监测方法具有较高的监测精度。

| Abstract: | In order to increase the efficiency and precision of erosion intensity measurement in soil and water conservation monitoring of development project,it tried to use 3-D laser scanner to monitor soil loss of spoil slopes of waste dump and compared with chain pin method which is most in use.The outcomes show that: a) the deviation of monitoring results of traditional chain pin method is 13.26% comparing with that of 3-D laser scanning calculation and;b) 3-D laser scanner has higher function of recording soil morphology variations and has higher monitoring precision comparing with traditional monitoring method. |
