摘　　要：LiDAR技术可以直接获取地表地物的三维信息,在森林参数估测方面具有独特的优势,因此,在森林资源调查中有着广泛应用。本文首先介绍了LiDAR系统组成和基本工作原理,然后详细分析了LiDAR技术定量提取树高、林分郁闭度和密度、蓄积量和生物量等森林参数的技术方法与研究进展,并对LiDAR数据在森林及其生态状况监测中的应用前景进行展望。LiDAR as an active remote sensing technology ,can provide 3D points cloud , has the unique advantage in evaluating the forest parameters, and has an extensive application in the forest resource investigation. LiDAR has shown its enormous potential in the forestry. In this paper, the components and basic principles of LiDAR system have been introduced, the estimation methods of tree height, canopy density, stock volume, biomass and etc. have been analysed , and the development in recent years has been summarized. At last, the prospect for application of LiDAR in forestry and ecological monitoring have been discussed .
