1利用激光雷达和多角度频谱成像仪数据估测森林垂直参数(英文)显示文摘植被的结构参数如植被高度、生物量、水平和垂直分布等,是影响陆地与大气能量交换乃至生物圈多样性的重要因素。多数遥感系统虽然可以提供植被水平结构的图像,但是不能提供植被成分垂直分布的信息。大尺度激光雷达仪器如LVIS产生的激光雷达信号,已成功地用于估计树高和森林生物量,然而大多数激光雷达仪器不具备图像能力,只能提供一个区域内的采样数据。其他的遥感数据如多角度高光谱、多频率多时相辐射计或雷达数据,可根据GLAS(Geoscience Laser Altimeter System)采样的测量用来推断出连续的森林结构区域覆盖参数。MISR(Multi-angle Imaging Spectrometer)对陆表多角度的成像能力,可以通过BRDF的各向异性提供植被的结构信息。结合激光雷达的垂直采样和MISR的图像,区域内乃至全球性的森林空间参数的成像是可能的。ICESat卫星上的GLAS数据、Terra卫星上的MISR数据为区域或全球性森林结构参数提供了可能。本文的研究目的是评估GLAS数据,分析类似于MISR的数据对森林结构参数的估计能力。本文中使用了LVIS、AirMISR和GLAS数据。通过对GLAS树高的测量与GLAS像元内来自LVIS的平均树高对比,发现它们是高度相关的。同时还探讨了多角度频谱成像仪数据预测树高信息的能力,这将在今后区域内森林结构参数映射加以研究。孙国清 Ranson K J 张钟军 2006遥感学报2006,10,4:16
