Abstract: Synthetic Aperture Radar (SAR),having a particular imaging mechanism that can acquire data at any time,has become more and more important for estimating forest biomass. In this research,based on field survey data,correlations between ALOS PALSAR dual polarization data backscattering coefficients (HH0,HV0 and V/HH0)and Yunnan pine forest volume from hilly regions were analyzed. A simple linear model,an exponential model,and a multiple regression model with terrain factors were developed. Results showed that correlation of the polarization ratio (V/HH0) to forest volume (r = -0.407) was higher than any single polarization (HH0 with r = 0.204 and HV0 with r = -0.242). Also,the multiple regression model with terrain factors was with highest accuracy.[Ch,3 fig. 2 tab. 12 ref.]
