Plant Diversity of Natural Forest in Songhuaba Reservoir
According to different altitude gradients and slope directions of natural forest communities in Songhuaba Reservoir,36 typical plots were set up for investigation.The species composition,plant flora,importance values of species at all levels of the community,and plant diversity of Songhuaba Reservoir were analyzed.The results showed that 300 species of vascular plants were investigated;the Pinus yun-nanensis population in arbor layer was absolutely dominant;the level of plant diversity of natural forest in Songhuaba Reservoir increased from arbor layer to shrub layer and then to herb layer;with the increase of altitude,the level of plant diversity first increased and then decreased;from sunny slope to semi shady slope and then to shady slope,the level of vegetation diversity first increased and then decreased.
