摘　　要：激光雷达技术可以直接获取地物的三维信息,在森林参数反演方面具有独特优势。近年来,机载激光雷达与地基激光雷达在林业上的应用取得很大进展,在森林调查中应用广泛。文中介绍了机载激光雷达与地基激光雷达在森林参数提取中的应用,并分析了两者的优缺点;概述了2种数据结合在森林参数反演中的应用,并对应用前景进行了展望。LiDAR （Light Detection and Ranging）, which can directly get access to the three-dimensional been made in its appli objects, enjoys unique advantages in forest parameter retrieval. Great progress has cation in forestry, especially in forest survey with ALS （Airborne Laser Scanning） and TLS （Terrestrial Laser Scanning）. This paper introduced and compared the advantages and disadvantages in the application of ALS and TLS to forest parameter retrieval. The combination of two kinds of data was used as an example to their use in forest parameter retrieval. Finally, the application prospect was prospected.
