Abstract: The plant composition in urban wetland parks is rich, and plays an active role for the urban environment. In Jinghu City Wetland Park(JCWP) in Shaoxing,the contents of metal elements(Al, Cr, Cu, K and Zn) in the soil, which collected from artificial garden and Meishan secondary forests, were compared by ICP-AES. Metal enrichments by different mycorrhizal hosts——Lolium perenne L.(AM), Monochasma sauatieri Franch(AM) and Vaccinium bracteatum Thumb.(ERM) in the secondary forests were examined. Based on the high through-put sequencing, the composition and structure of root fungal communities of three plant species were determined, and the relationship between them and metal elements in soil was analyzed. The results showed that:(1)the contents of five metal elements in the soil from the artificial park were significantly higher than those in the soil under the secondary forest; (2)V.bracteatum had a stronger ability to enrich Al, L.perenne and M.sauatieri both were good at Cr enrichment; (3)The fungi associated with root of these plants were mainly composed of Ascomycota, while Basidiomycota was also prefer to stay with V.bracteatum hair roots. The putative AM fungi were less in fungal community structure together with their hosts, however the putative ERM fungi——Helotiales and Sebacinales were popular in V.bracteatum samples, and there was no significant correlation with these metal elements. The soil environment under the secondary forest in JCWP keeps well.

Key words: fungal community, metal elements, arbuscular mycorrhiza(AM), ericoid mycorrhiza(ERM), Vaccinium bracteatum Thumb.
