【Abstract】 In this paper, nine regression equations for pre-estimating biomass arecompared one another, comparative results showed that the regression equation lgW = 1.750 + 2.5251gR is the most suitable model to estimate above-ground biomass of the artificial Caragana kroshinskii shrub. In addition, the use of this model was discussed,更多还原
