Equation

As printed (Table 6 (MS-3), Dahurian larch, foliage row; model form Eq. (14) structure)

Wf = e^β40 · D^β41 · H^β42; Dahurian larch | Foliage | -2.5753 | 2.4388 | -1.1785

In this library's units, ready to compute (kg)

Foliage biomass = exp(-2.5753 + 2.4388 * ln(D) - 1.1785 * ln(H))
D
Diameter at breast height (1.3 m), cm
H
Total tree height, m

Dahurian larch, additive system MS-3 (Table 6); W = exp(b0) * D^b1 * H^b2 (Eqs. 17 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).
