摘　　要：高光谱遥感技术已成为林业遥感领域的前沿技术之一。回顾国内外高光谱遥感技术在林业信息提取中的研究进展,总结归纳了森林树种高光谱分类与识别、森林生态物理参数高光谱反演与提取、林木养分元素高光谱监测与诊断、森林郁闭度信息高光谱提取、森林灾害高光谱监测五个主要研究方面。在此基础上,文章指出了在林业遥感应用中高光谱技术尚待解决的关键问题,并阐述了可能解决问题的途径。最后对林业高光谱遥感技术的应用前景作了展望。The hyperspectral remote sensing technology has become one of the leading technologies in forestry remote sensing domain. In the present review paper, the advances in researches on hyperspectral remote sensing technology in forestry information extraction both at home and abroad were reviewed, and the five main research aspects including the hyperspectral classification and recognition of forest tree species, the hyperspectral inversion and extraction of forest ecological physical param- eters, the hyperspectral monitoring and diagnosis of forest nutrient element, the forest crown density information extraction and the hyperspectral monitoring of forest disasters were summarized. The unresolved problems of hyperspectral technology in the forestry remote sensing applications were pointed out and the possible ways to solve these problems were expounded. Finally, the application prospect of hyperspectral remote sensing technology in forestry was analyzed.
