Sprucefir and broadleaved mixed forests, sprucefir mixed forests and near primitive sprucefir forests are representative of the forest communities in Changbai Mountains of northeastern China. Based on investigation data from each plot of the above three typical sprucefir forests, one point pattern analysis method—Oring statistics was used to analyze the spatial patterns of dominant species and the spatial correlations among different species were studied. The results showed that the random distribution appeared widely in the three communities, the aggregated distribution decreased, while the random and regular distributions increased in all major species. The phenomenon of negative correlations increased between Pinus koraiensis and P. koraiensis, P. koraiensis and Abies nephrolepis, A. nephrolepis and P. koraiensis from the sprucefir and broadleaved mixed forests to the sprucefir mixed forests and near primitive sprucefir forests. Tilia amurensis was clumped significantly at small scales and a random distribution showed at other scales, the regularity of distribution was not obvious in other species.
