机载激光雷达在森林资源调查中的应用与展望

Application and Prospect of Airborne LiDAR in Forest Resource Survey

近年来机载激光雷达技术取得了快速发展,已经成为森林资源调查领域的重要工具。介绍利用机载激光雷达进行森林资源调查的原理,阐述其在单木因子调查、林分因子调查中的应用,总结在单木冠幅调查、单木树高调查、林分平均树高调查、林分叶面积指数调查、林分郁闭度调查、林分生物量调查等方面机载激光雷达的相关数据处理方法,最后分析机载激光雷达在森林资源调查当中的不足,并对这一技术在森林资源调查的未来发展前景进行展望。

In recent years,airborne lidar technology has made rapid development and has become an important tool in the field of forest resource survey.In this paper,the principle of airborne lidar for forest resource survey is introduced and used,and its application in single tree factor survey and stand factor survey is described.The data processing methods of airborne lidar in single canopy survey,single tree height survey,stand average tree height survey,stand leaf area index survey,stand canopy density survey,stand biomass survey and other aspects were summarized.Finally,the shortcomings of current forest resource survey were analyzed.The future development prospect of airborne lidar in forest resource survey is also prospected.
