摘　　要：对植苗造林生长状况进行监测,调查植苗成活率,监测成活树苗的健康状况,分析死亡树苗未成活的原因等,是一项重要任务。以常规手段在山区进行现场调查,费时费力,费用较高。针对于此,以无人机载LiDAR扫描技术方法对植苗造林区进行精确扫描,获取高精度点云、精细化数字高程模型和高分辨率正射影像图,进行集成分析,提高监测技术水平和质量,可有效提高效率和准确度。The monitoring of growth of afforestation,including the survival rate of tree planting,the health status of surviving trees and analyzing the reasons for the failure of dead trees to survive,is an important task.For the time being,however,conducting field investigation in mountainous area by conventional means is time-consuming,laborious and high operating cost.In view of this,the UAVborne LiDAR scanning technology is used to accurately scan the afforestation area,to obtain high-precision point clouds,fine digital elevation models and high-resolution digital orthophoto images,and then conduct integration analysis to improve the monitoring technology level and quality,which can effectively improve the monitoring efficiency and accuracy.
