西藏三种疯草高光谱特征比较
Hyperspectral Features of the Three Locoweed in Tibet
摘要
Abstract
In order to research the spectral characteristics of locoweed in Tibet ,canopy spectral reflectance of Astragalus strictus ,Oxytropis sericopetala and Oxytropis glacialis were measured with ASD field Hand-Held spectroradiometers .The results showed that the three kind of locoweed had the same spectral curve character-istics with vegetation ,but they were great different during wave band 552 ,670 and 760 nm .Meanwhile ,the first order differential of their original spectrum showed that differences of red edge slope between those three kinds of locoweed were very significant .This research provided a theory evidence for monitoring spatial distribution of locoweed in large area with remote sensing technology .关键词
