| 英文摘要 | Using various biomass factors, such as biomass expansion factor (BEF) and biomass conversion and expansion factor (BCEF), yields different results for estimating forest biomass. Therefore, ensuring compatibility between total biomass and its components when employing different biomass factors is crucial for developing a set of rapid and efficient models for large-scale biomass calculation. In this study, allometric equations were utilized to construct independent models and the proportional values (root-to-shoot ratio (R-ra), crown-to-stem ratio (R-cs), bark-to-wood ratio (R-bw), foliage-to-bark ratio (R-fb), and wood biomass-to-wood volume (rho)) by using the mean height (H-m) and the mean diameter at breast height (D-g) of 98 Pinus densata plots in Shangri-La, Yunnan province, China. The compatible methods were applied to reveal the compatibility between the total biomass and each component's biomass. The results showed the following: (1) Both the independent model and compatible model had a higher accuracy. The values were greater than 0.7 overall, but the foliage biomass accuracy was only 0.2. The total biomass and the component biomass showed compatibility. (2) The accuracy of BEF and BCEF exceeded 0.87 and the total error was less than 0.1 for most components. (3) The mean BEF (1.6) was greater than that of the Intergovernmental Panel on Climate Change (IPCC) (M = 1.3), and the mean BCEF was smaller than that of the IPCC; the values were 0.6 and 0.7, respectively. The range of BEF (1.4-2.1) and BCEF (0.44-0.89) were all within the range of the IPCC (1.15-3.2, 0.4-1.0). This study provides a more convenient and accurate method for calculating conversion coefficients (BEF and BCEF), especially when only R-cs data is available. |
