Study On Biomass Estimation Model Of Larix Olgensis

Using above ground biomass of Larix olgensis plantation as study objects in DoZheleng Reiver forest farm, stand above ground biomass information of 34 plots were collected in the way of sample tree harvest. Biomass information of 29 plots were selected to establish biomass model with stand factor and TM RS image information and nonlinear factor respectively, and the rest 5 plots were used for model checking and error analysis. The results showed that:above ground biomass of Larix olgensis can be fitted by remote-sensing factor or stand factor model; The stand factor linear model in the estimation of above ground biomass Young was high accuracy (P stands= 94.33%>PRS=PNL=92.32%).while the test error is small (MRE stand=6%
