We examined the soil fauna community composition and structure of Poyang Lake beach wetlands using the modified Tullgren and Baermann methods during September and December 2015. A total of 3755 individuals were obtained from 2 samplings, which were found to belong to 7 classes, 8 orders, 3 suborders, and 17 families. Among these, the Oribatida, Prostigmata, Nematoda, and Onychiuridae were dominant. The functional groups of soil animals included omnivores, saprozoics, predators, and phytophages. Analysis results of the soil fauna composition and diversity showed that the soil animals were mainly concentrated at the 0–10 cm depth, presenting as a significant surface convergence phenomenon. |
