Abstract
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.
