The soil microbial community composition of bare land and six kinds of plant
vegetation were investigated in the Yellow River Delta Wetland, China. We analyzed the diversity
and function of the soil microbial community composition using high-throughput sequencing
technology in the different vegetation cover lands. Tamarix chinensis (T. chinensis) had the highest
microbial richness and Aeluropus sinensis (A. sinensis) had the highest microbial diversity. Phragmites
australis (P. australis) had the highest proportion of Pseudomonas (9.34%) showed the strongest
denitrification and phosphorus-accumulation ability. T. chinensis had the highest read number
of ammonia oxidizing bacteria (AOB) (41) indicated the highest ability of ammonia-oxidizing.
The read number of Diazotrophs under T. chinensis (17) and Suaeda salsa (S. salsa) (88) was
significantly higher than control (p < 0.01) mean the strongest nitrogen fixation effects. The
relative abundance of anammox bacteria (273) was highest in A. sinensis. The read number of
phosphorus-accumulating bacteria (PAOs) in P. australis, T. chinensis, S. salsa and A. sinensis were
significantly higher than control (p < 0.01).
