Equation
As printed (Table 5 (forms in Eq. 4-7 and Section 3.2))
AGB = Bcu + Bbr + Ble = a1 × Db1 + a2 × Db2 + a3 × Db3 (parameters Bcu = a1 × Db1: a1 0.098137 b1 2.365691; Bbr = a2 × Db2: a2 0.052164 b2 2.004830; Ble = a3 × Db3: a3 0.030439 b3 1.741870)
In this library's units, ready to compute (kg)
Aboveground biomass = 0.098137 * D^2.365691 + 0.052164 * D^2.004830 + 0.030439 * D^1.741870D- Diameter at breast height (1.3 m), cm
One bamboo culm (plant) per record; D is culm diameter at breast height. Biomass in kg dry mass per plant. Component equations are fitted simultaneously (SUR) so the AGB equation is the sum of the three components. Parameters as printed in Table 5; the paper reports adjusted R2 only, so r2 is omitted.
