Rhizosphere microbial community diversity of different plants Phragmites australis, Typha latifolia, and Lolium perenne grown in constructed wetland was studied by plate count methods and PCR-DGGE. The results were as followed.Rhizosphere of different plants was different in community structure and microbial quantity. The microbial quantities in rhizosphere zone were significantly different from those in non-rhizosphere zone (P<0.05). Moreover, there were different community structure and dominant populations between rhizosphere and non-rhizosphere. Phragmites australis rhizosphere had the largest number of common species and species evenness. At the same time, it had the most significant rhizosphereeffect (R/S).The biggest different diversity index between rhizosphere and non-rhizosphere was also in P. australis, which showed that it could better influence the enrichment and distribution of soil microbes, and improve the microbial communitiy diversity.
