Equation
As printed (Table 5 (MS-2), Dahurian larch, foliage row; model form Eq. (14) structure)
Wf = e^β40 · D^β41; Dahurian larch | Foliage | -3.2145 | 1.5199
In this library's units, ready to compute (kg)
Foliage biomass = exp(-3.2145 + 1.5199 * ln(D))D- Diameter at breast height (1.3 m), cm
Dahurian larch, additive system MS-2 (Table 5); W = exp(b0) * D^b1 (Eqs. 16 form per Table caption). Ranges and n from Table 2. The b0 column is the exponent of e (W = e^b0 ...), as in Eq. (14). Stem includes bark. Root excludes fine roots <5 mm. No R2 recorded (adjusted R2 only).
