Assessment of Cashew and Rubber Plants Biophysical Parameters Based on ALOS/PALSAR Data

抄録

        Information about the biophysical parameters of plants is useful for the prediction of growth, yield, rotation cycle, carbon sequestration and management practices. In this study, we have investigated different biophysical parameters of cashew and rubber plants using Advanced Land Observing Satellite Phased Array L-band Synthetic Aperture Radar (ALOS/PALSAR) backscattering properties in Cambodia. The result shows the plants’ structural dependence on PALSAR data. The backscattering coefficient (σ⁰) has different response for both plantation types because of differences in their biophysical parameters. This dependency of σ⁰ shows different behaviour of PALSAR dual polarimetric data. The σ⁰ HV polarization shows fairly good correlation with the biomass, height, DBH and age of cashew and rubber plantations up to the saturation limit. [This abstract is not included in the PDF]
