Abstract

The purpose was to construct an estimation model of the crown diameter(CD) of Populus euphratica and aboveground biomass (AGB).328 sample trees were selected from the sample plots of P.euphratica distribution area,and the CD of P.euphratica by unmanned aerial vehicle (UAV) remote sensing data was taken as the independent variable,combined with the aboveground fresh biomass obtained from the P.euphratica biomass model,and,the estimation model of different function forms is constructed and precision analysis is performed through correlation and regression analysis methods.The best models for estimating the biomass of P.euphratica with UAV remote sensing were the cubic functions in Moyu County,Bachu County,and Luntai County.The accuracy was 94.93%,95.63%,and 92.24% respectively.The optimal estimation model for aboveground biomass of different ages of P.euphratica is determined.It was feasible to estimate the biomass by using UAV remote sensing,which provided technical support for the management and ecological value evaluation of P.euphratica.

Key words： Populus euphratica; crown width; aboveground biomass; UAV remote sensing; model
