英文摘要	Plant invasion has been reported to alter ecosystem carbon (C) and nitrogen (N) cycling processes and pools. The mechanisms involved in how plant invasion affects the soil microbial community-the primary mediator of soil C and N cycling-remain poorly understood. The objective of this study was therefore to evaluate the effect of plant invasion on the soil microbial community in a coastal wetland of eastern China. We investigated the impact of an exotic C-4 perennial grass, Spartina alterniflora, on the soil microbial community structure based on phospholipid fatty acids (PLFAs) analysis and chloroform fumigation-extraction by comparing it to that of bare flat and native C-3 plants Suaeda salsa and Phragmites australis communities. Spartina alterniflora invasion significantly increased soil microbial biomass C and the total and various types of PLFAs compared with bare flat, Suaeda salsa and Phragmites australis communities. Increased concentrations of soil moisture, electrical conductivity, water-soluble organic carbon (WSOC), and total, labile and recalcitrant soil organic C and N, and decreased soil pH in Spartina alterniflora community explained 65.9 % of the total variability in the PLFAs. WSOC and soil labile organic N were strongly correlated with PLFAs, whereas soil pH was negatively related to PLFAs. A 10-year Spartina alterniflora invasion significantly altered soil microbial biomass and community structure by increasing available substrate. The changes in soil microbial biomass and community structure may in turn enhance soil C and N sequestration in a coastal wetland of eastern China.
