3.2.2 Diversity Distribution at Two
Scales
Vegetation diversity is relatively low over the study area, with similar
diversity at both scales. The 10m x 10m scale provides more detailed and
accurate information on vegetation diversity compared to the 30m x 30m
scale (Table 2 and Figure 8). At
the 10m scale, the Margalef index indicates a moderate level of species
richness, with a mean of 0.760; the Pielou index indicates uneven
species distribution, with a mean of 0.295; the Simpson index is more
sensitive to the enrichment of species, with a mean of 0.210, indicating
a relatively low diversity; the Shannon-Wiener index is most closely
related to species richness, with a mean of 0.395.
