In this study, the communities of Picea crasslia, Larix principis-rupprechtⅡ, Betula platyphylla and Picea crasslia-Betula platyphylla were selected as objects. In order to show growth of herb community niche of different plantation communities from view of niche, the niche breadth and niche overlapping of herb community were measured by means of levins niche breadth and pianka niche overlapping indexes in different plantation communities. It showed that wide ecological amplitude of species was different in different plantation communities. Broad-leaved mixed forest was the best for vegetation development and regeneration. The niche overlap index suggested that the species with big niche breadth often had big niche overlapping. But in some plantation communities, the species with narrow niche breadth had big niche overlapping. This phenomenon may be due to different herb community competition with each other for limited environmental resources. Herb community of broad-leaved mixed forest can make better use of resources.
