高光谱遥感森林信息提取研究进展

针对高光谱遥感技术森林信息提取,详细论述了国内外利用高光谱遥感数据进行森林类型识别、森林郁闭度估算和森林叶面积指数估测等森林物理参量,以及森林化学参量估计和森林健康状态评价等方面的应用研究状况,最后对高光谱遥感森林应用的发展趋势作了探讨.

Research Advance in Forest Informa tion Extractionfrom Hyoerspectral Remote Sensing Data

With the development of remote sensing technology, especially the app lication of hyperspectral remotesensing data, more studies were focused on the investigation of forest information p roduction using hyperspectralremote sensing data. In this paper, it described the current state of forest biophysical and biochemical parametersderived from hyperspectral remote sensing data, such as forest species determining, canopy closure estimation andforest leave area index detection. This paper p resented the future trend of the application of hyperspectral remotesensing in forestry.
