communities
tabulaeformis communities with three tending practices, the highest species abundance index appears with tending and shelterwood cutting and the highest evenness index and species diversity appears with closed tending.
      
tabulaeformis populations in Huanglongshan Mountain so that the communities will develop continuously.
      
This result agreed with the phenomenon of desertification reversion, vegetation restoration and dominant communities' formation.
      
Biomass structure and nitrogen, phosphorus nutrient of Calamagrostis angustifolia populations in different communities of Sanjia
      
Calamagrostis angustifolia is the dominant species in the typical meadow and marsh meadow communities of Sanjiang Plain.
      
angustifolia organs in the two types of wetland communities was distinctly different, which could be described by polynomial.
      
Genetic diversity of Lithocarpus harlandii populations in three forest communities with different succession stages
      
harlandii was influenced not only by the biological characteristics of this species, but also by the microenvironment of different communities.
      
Structural diversity of forest communities on Baihuashan Mountain, Beijing
      
New structural indices were constructed, calculated and compared among different communities.
      
On the basis of previous work, structural diversity of forest communities at the stand level was described by a vertical complexity index and a horizontal heterogeneity index.
      
The results show that, in natural forests, structural diversity of pioneer communities is much lower than in late successive communities.
      
The communities of Larix chinensis and their ecotone in Qinling Mountains were investigated by sampling belt method.
      
Species richness, Simpson diversity, Shannon-Weiner diversity, PIE and Pielou evenness indices of vascular plants in their communities and ecotone were calculated.
      
Structure and composition of the communities in 6 sampling belts within the sites were analyzed.
      
Soil animal communities at five succession stages in the litter of the evergreen broad-leaved forest in Tiantong, China
      
Soil animal communities in the five plant communities at different succession stages were investigated during the 2003 winter.
      
The results indicated that there was a distinctive vertical distribution of the soil animal communities in the forest litter layer, but it differed from that in soil below the litter layer.
      
Many studies have demonstrated the changes in the spatial patterns of plant and animal communities with respect to habitat fragmentation.
      
Insular communities tend to exhibit some special patterns in connection with the characteristics of island habitats.
