摘要
对激光雷达技术在森林资源监测方面的运用前景、局限性和研究进展进行总结,并研究激光雷达技术在森林资源监测方面的成果。结果表明:激光雷达技术植物资源方面的监测主要为森林的整体结构高度、植被的具体高度及森林中植被的占有密度,生物密度方面的监测一般应用小光斑系统,温带气候的森林植被叶面积较为均衡,可采用常规的激光检测进行监测。由于应用普通激光雷达技术对森林资源进行监测时,会受到雷达运行空间不足、费用高昂、检测数据量有限等问题的约束,提出应形成一套费用低、监测数据量大、运行空间充足的机载系统,提高雷达的灵活性。
This paper summarized the application prospect,limitations,research progress and achievements of lidar technology in forest resources monitoring.The results showed that the monitoring of plant resources by lidar technology mainly included the overall structural height of the forest,the height of specific vegetation,and the density of vegetation in the forest.The monitoring of biological density generally used small light spot system,and the leaf area of forest vegetation in temperate climate was relatively balanced,which could use conventional laser for monitoring.As the application of common lidar technology to forest resources monitoring was constrained by the problems of insufficient radar operation space,high cost and limited detection data,this paper proposed that a set of airborne system with low cost,large monitoring data and sufficient operation space should be formed to improve the flexibility of radar.
