Analysis on forest plant diversity in the Three Gorges Reservoir Area

Abstract

Abstract: The forest resource is rich in the Three Gorges Reservoir Area, according to the investigation data in the area, there are 41 kinds of forest communities, and the trend of the richness index, species diversity index and evenness index is not regular. In the coniferous forest, the trend of the richness index in different layer along the community is shrub >herb>tree. In the evergreen broadleaf forest, the trend is shrub > tree > herb. In the deciduous broadleaf forest, especially the typical Quercus forest, the trend is shrub >herb and tree, but in the herb layer and the tree layer, the trend fluctuates. The trend of the species diversity index is tree < herb and shrub, but in the herb layer and the shrub layer, the trend fluctuates. In other communities, the trend of all indices along the community fluctuates too. One reason may be the different natural environment and different growth condition of the community, and the long time strong disturbance of the human population is another important factor that couldn't be ignored.

Key words: Forest community, Species diversity, Three Gorges Reservoir Area, trace metal contamination, landscape heterogeneity, multi-scale, partial redundancy analysis
