Abstract: Based on field investigation and relative data,the composition of grassland plant resources at the middle section on the northern slope of Tianshan Mountain was analyzed.The results showed that the complicated ecological and geographical conditions resulted in abundan plant resources in this area,and the maximum of the species richness appeared in the alpine meadow.The heterogeneity of species along the vertical zone and the diversity of habitats at different parts could be reflected obviously by β index.The vertical differentiation of grassland species resulted from the habitat and environment evolvement.The conclusion could provide a scientific foundation to the conservation of biodiversity in this region.
