Effects of Land Use Conversion on the Soil Microbial Community Composition and Functionality in the Urban Wetlands of North-Eastern China

Urban wetlands are undergoing intensive conversion from natural to farmlands, woodlands, and even alkaline land. This study aimed determine the effects of land on soil microbial communities urban in hinterland Songnen Plain, Northeastern China. Soil samples were collected various sites Longfeng wetland, including swamp wetland (SW), meadow (MW), woodland (WL), farmland (FL), (AL). High-throughput sequencing followed by bioinformatic analysis was conducted evaluate structure, composition, function bacterial fungal communities. The most dominant phylum among land-use types Proteobacteria Ascomycota, respectively. In addition, diversity functions varied significantly across different types. However, no remarkable differences observed under Edaphic parameters, exchange sodium percent (ESP) total nitrogen (TN), remarkably influenced abundance These results show that type shapes aspects communities, physicochemical properties, taxa potential functional genes, correlation with environmental factors. provides reliable data guide use management supervision decision-makers this region.
