大兴安岭地区森林叶片反射率的反演
Inversion of Forest Foliage Reflectance in Daxing'anling Region
摘要
Abstract
As one of the most important vegetation parameters,foliage reflectance plays a significant role in forest research.The pixel information extracted from remote sensing images is the canopy reflectance.In order to obtain the foliage reflectance,a lookup table between canopy reflectance and foliage reflectance,which is built from simulating canopy reflectance by MODIS Surface Reflectance products(MOD09A1),Leaf Area Index products(MOD15A2),land cover types(MCD12Q1)combined with four-scale model and PROSOECT model,is used to invert the foliage reflectance in Daxing'anling region in August,2015.A scale conversion from canopy reflectance to foliage reflectance is accomplished.The foliage reflectance data acquired by SVC-1024i device in the forest is used to do accuracy test.Results show that the field data and foliage reflectance inverted by look-up table have good correlation in Red and Near-infrared bands(R2 is 0.789 and 0.796),which means using look-up table based on four-scale model to invert foliage reflectance is feasible.关键词
