内容 研究概要:Ability of visible infrared radiometer for stand parameter estimation was evaluated. The diameter at breast height, tree height, timber volume and so on were selected as the stand parameters. High correlation coefficients between those stand parameters and remote sensing data were observed in some channels. Though channels with stronger absorption by chlorophyll in the visible channels showed lower correlation, other channels like at the green peak and the red edge showed higher correlation with the stand parameters. The tendency was observed for the imagery observed in early August and early September, then those wavelength were seemed useful to estimate woody biomass Though high correlation between leaf biomass and the normalized difference vegetation index (NDVI) was reported, no clear relationship was observed between the NDVI and stand parameters. However, high correlation coefficients exceeding 0.8 were observed between stand parameters and a normalized ratio between the 730nm and the 2200nm channels (ND730& 2200), and little observation angle effect was identified on the ND730& 2200. Thus the index was probably useful for biomass estimation of evergreen coniferous forests using wide view angle sensor imagery.
