以内蒙古大兴安岭森林生态系统国家野外科学观测研究站为研究区，通过2012年8月至9月获取的机载激光雷达数据与地面同步调查样地数据，构建林分平均高反演模型和林分内郁闭度反演模型。结果表明：混交林、阔叶林和针叶林的林分平均高估测精度依次为95．66％、94．11％和90．71％，林分郁闭度估测精度依次为92．73％、56．62％和85．19％。不同森林类型的林分平均高与郁闭度反演精度存在显著性差异。

In the Daxing ’ an Mountains in Inner Mongolia State Forest Ecosystem Station , with the Airborne LiDAR data and field measured plots data in August to September in 2012, we built the forest height model and forest canopy closure mod-el, respectively.The forest height accuracies in mixed forests , broad-leaved and coniferous forest were 95.66%, 94.11%and 90.71%, respectively, and the forest canopy closure accuracies were 92.73%, 56.62%and 85.19%, respectively. There was significant difference in forest height and forest canopy closure inversion on different forest types .
