Estimating the dry matter of grasses and shrubs in semi-arid zones using visible and near-infrared wavelengths recorded by high resolution aerial photographs

摘要：

Introduction Non-destructive estimates of plant biomass in semi-arid grasslands were for long hampered by the availability of high resolution radiation data.Recently IKONOS and QUICKBIRD satellite images have become available for all areas worldwide but their costs are in contrast to LANDSAT and SPOT datasets often prohibitive.
