Abstract：This paper is devoted to disclose the effects of Spartina alterniflora invasion on soil organic carbon contents in the bare tidal flat. We chose the bare tidal flat and S. alterniflora wetlands of Minjiang River estuary as the research objects. The contents of soil organic carbon and soil labile organic carbon at different soil horizons of typical bare tidal flat and S. alterniflora wetlands were determined and the soil physicochemical properties were also analyzed. The results indicated that the contents of soil organic carbon at different soil depths (0 -60 cm) ranged from 0.95 to 12.43 g/ kg in the bare tidal flat and and from 1.45 to 10.04 g/ kg in S. alterniflora wetlands, with the mean values of 4.03 and 4.35 g/ kg, respectively. Compared with the bare tidal flat, the mean contents of soil microbial biomass carbon, dissolved organic carbon and light fraction organic carbon in soils (0 -60 cm) of S. alterniflora wetlands increased by 12.76%, 40.86% and 12.62%, respectively. The contents of easily oxidizable carbon changed very little. The results of this study showed that the invasion of S. alterniflora had increased the contents of soil organic carbon and soil labile organic carbon, but the influence was not significant.
