Abstract: In this paper, it selects the main of the area forest dominant species communities in this area as the object of this study to analyze the spatial distribution population patterns of the dominant species diversity distribution law of Daxinganling forest community from the stand scale. The major result of this article were hereby described as follows: Daxinganling the total number of the species distribution range of 0-28 species, and the variation on the vertical structure of community showed the herbaceous layer species richness index above the shrub layer and tree layer.The highest species richness appeared in Larix gmelinii communities of Alihexilingti forest with more species of shrub and herb layers. The lowest species richness appeared in Larix gmelinii communities of Keyihekuya forest with less herb layer species.
