Leaf area indices (LAIs) of stands in natural forests and forests disturbed by felling and fires in Primorsky Krai have been determined using data on the foliage phytomass and specific leaf area (SLA) from 44 sample plots. The LAI of forest stands disturbed by fires and felling is more than 30% lower than that of intact forests, which are structurally close to native coniferous–broadleaf stands. The leaf area index is significantly correlated with the stand volume (R2 = 0.68); however, it should be considered as an independent indicator and its calculation based on stand taxation characteristics involves high uncertainties.

滨海边疆区天然林和干扰林林分的叶面积指数

使用来自 44 个样地的树叶植物量和比叶面积 (SLA) 的数据，确定了滨海边疆区天然林和受砍伐和火灾干扰的森林中林分的叶面积指数 (LAI)。受火灾和砍伐干扰的林分的 LAI 比结构接近天然针阔叶林的完整林低 30% 以上。叶面积指数与林分体积显着相关（R2 = 0.68）；然而，它应该被视为一个独立的指标，其基于关税税率特征的计算涉及高度不确定性。
