英文摘要	This study analyzed the variations of soil organic carbon (SOC), total nitrogen (TN), and total phosphorus (TP) with depth in coastal wetlands of Laizhou Bay, Bohai Sea. Generally, average contents of SOC and TN were higher at tidal flooding Guangrao wetland (GRA) than those at Changyi (CY) wetland where the tidal can rarely reached. Among the five profiles, higher variations of SOC and TN were observed in CYB1 and CYB2, where the TP contents showed lower variations. SOC showed a rapid decrease with depth in CYB1 and CYB2, whereas they tended to increase with depth in GRA1 and GRA2. Vertical distributions of TN were significantly correlated with SOC in profile GRA1, CYB1, and CYB2. However, no clear trend was found on the vertical variations of TP. Additionally, C, N, and P ecological stoichiometry in these two coastal wetlands had high complexities within wetland. The C/N ratios were generally higher, while the C/P ratios and the N/P ratios were comparatively low, indicating the coastal wetland biogeochemical processes were more limited by N and P, with the former may being the primary factor. Our results also indicated that both vegetation coverage and tidal flooding were important in the biogeochemical processes of these coastal wetlands.
