本文以东北林业大学老山生态站阳坡和阴坡的人工林红松为研究对象，基于分形理论，从非线性角度出发，对红松木材碳素储存量进行分形分析，研究其规律性变化，旨在明确不同地理位置间木材碳素储存能力的差异。研究结果表明，老山生态站阳坡和阴坡红松木材碳素储存量的径向变异趋势相近；阴坡的碳素储存能力高于阳坡；阴坡红松幼龄材和成熟材碳素储存量的分形维数平均值明显高于阳坡，其碳素储存量的梯度分布较阳坡更复杂，且木材碳素储存效果明显优于阳坡。这为选择有利于提高木材碳素储存效果的人工林红松立地条件提供了理论依据。

The paper took the man-planted Pinus Koraiensis of Northeast Forestry University Laoshan Forest Farm in sunny slope and shady slope as research object，based on the fractal theory，studied the Pinus Koraiensis wood carbon storage through fractal analysis from the nonlinear perspective，and discussed the regular change. It aimed to ensure the difference among the capacity of wood carbon storage under different geographical location. The research results showed that，the radial variation trend of Pinus Koraiensis carbon storage of Laoshan Forest Farm in sunny slope was close to the shady slope，and the carbon storage capacity of shady slope was higher than that of sunny slope. The mean fractal dimension of juvenile wood and mature wood carbon storage of shady slope was obviously higher than that of sunny slope，its gradient distribution of carbon storage was more complex than sunny slope and the effect of carbon storage was superior to sunny slope. Thus，it would provide the theoretical basis for choosing the site conditions of man-planted Pinus Koraiensis which was beneficial to improve the wood carbon storage effect.
