摘要	Seagrasses play an important role in the geochemical cycling of elements in coastal ecosystems. Eelgrass (Zostera marina L.) is a marine foundation species essential for coastal ecosystem services in the temperate northern hemisphere. The elemental (C, N, and P) and isotope (delta C-13 and delta N-15) contents of eelgrass tissues were measured at nine sampling sites across northern China. Trends at temporal and spatial scales were analyzed to examine temporal-spatial variations in seagrass characteristics, and relationships between different tissues were also analyzed to identify a valuable ecological indicator. Elemental contents (N and P) of eelgrass were variable and demonstrated marked seasonal variations, while the isotope content (delta C-13 and delta N-15) demonstrated marked spatial variations. Elemental contents (N and P) in eelgrass tissues showed a clear annual trend with minima in summer and maxima in spring-winter in Swan Lake. Mean N contents (%) of leaf blades and leaf sheaths in Swan Lake were 2.56 +/- 0.89 and 2.53 +/- 0.96, respectively, and mean P contents of blades and sheaths were 0.31 +/- 0.13 and 0.41 +/- 0.17, respectively. N and P contents were higher in aboveground than in belowground tissues; due to C stability, C/N and C/P were lower in aboveground than in belowgmund tissues. Among different eelgrass populations, the ranges of delta N-15 isotope ratios in leaf blades and leaf sheaths were 5.57-9.64 and 5.89-9.79, respectively. Elemental (N and P) and isotope (delta C-13 and delta N-15) contents of leaf sheaths were positively correlated with those of blades; this was evident regardless of the season and site, suggesting that the sheath elemental and stable isotope content could be a valuable indicator of that in leaf blades for seagrass ecosystem geochemical research.
