The same trend was observed using the evenness index.
The following indices were used: richness; Shannon's diversity index; Simpson diversity index; Shannon's evenness index; Simpson's evenness index.
Richness, Simpson's evenness index, and cover were calculated for the total vascular plant community.
The diversity and evenness index continually enhanced, the diversity increased from 0.73 in 1986 to 0.84 in 2006.
Faunal biodiversity represented by Pielou's evenness index was more important than taxa richness and individual abundances of taxa.
The evenness index was in an increasing trend while the dominance index was in a decreasing trend.
The landscape indices, such as patch size, patch fractal dimension, diversity index and evenness index, were calculated.
The decrease of Shannon's diversity index and evenness index manifested intensive management and reconstruction of landscape by human beings.
The richness (S), Menhinick's index (M), Shannon index (H), maximum Shannon index (Hmax) and evenness index (E) were used to explain pedodiversity in the study area.
Species diversity of overstory, understory, and herbaceous layer species was evaluated using species richness (S), Shannon Wiener's index of diversity (H′), and Pielou's evenness index (E).
This was supported by decreasing tendencies of patch indices SHDI (Shannon's diversity index), SHEI (Shannon's evenness index), and IJI (Interspersion and juxtaposition index).
