Effects of Habitat Types on Macroinvertebrates Assemblages Structure: Case Study of Sun Island Bund Wetland

Figure 7

Principal component analysis (PCA) of biological indices comparison between three types of vegetation. The values of the index (D) and index (d) were the highest in the types of S-F-E vegetation, and next were in the types of F-E vegetation, and the two indices were lowest in the types of Emergent vegetation (E). While the values of the index () were highest in the types of S-F-E vegetation, next were in Emergent vegetation (E), and the values of Pielou evenness index (J) were highest in the types of F-E vegetation and the lowest in the types of S-F-E vegetation. S-F-E, Submergent-flouting-emergent vegetation; F-E, Flouting-emergent vegetation; E, Emergent vegetation. D, Simpson diversity index; d, Margalef richness index; , Shannon-Weiner diversity index; J, Pielou evenness index. S-H, Silt-humus; M-G, Mud-gravel; M-S, Mud-sand.
