Study on the Species Diversity in Undergrow Vegetation of Different Types of Artificial Robinia pseudoacacia L. Forests in Mout Tai Scenery Area
The vertical structure and species diversity of different types of artificial R. pseudoacacia forest commu?nities were studies. The results were as follows:(1)Shrub layers’height and coverage and herb layers’height were mixed R. pseudoacacia and Platycladus orientalis forest>mixed R. pseudoacacia and Pinus tabulaeformis for?est>R. pseudoacacia forest,but herb layers’coverage was mixed R. pseudoacacia and P. tabulaeformis forest>mixed R. pseudoacacia and P. orientalis forest>R. pseudoacacia forest.(2)The R. pseudoacacia forest had the low?est richness and diversity in shrub and herb layers,but had the highest evenness;mixed P. tabulaeformis and R. pseudoacacia forest had a higher richness,diversity and evenness than R. pseudoacacia and P. orientalis for?est except the Simpson index in shrub layer.(3) Mixed forest should be constructed in order to improve the eco?logical function.
