摘要	We sampled the surface sediments of the East China Sea shelf (ECSS) in spring and autumn, 2014, and analyzed the biogenic element concentrations and stable carbon (delta C-13) and nitrogen (delta N-15) isotopic compositions to study the distribution and seasonal variations of sedimentary organic matter (OM). The average concentrations of TOC, TN and OP in autumn decreased obviously compared with those in spring. The increase of delta N-15 values in autumn indicated the priority utilization of N-14 by bacterial decomposition activity. The values of delta C-13 were used to trace organic matter sources. The estimated percentages for terrestrial OM were in the range of 0-34.6%. They generally decreased seaward in nearshore areas, indicating the decrease of terrigenous influence. There was an obvious tongue-shaped region with relatively low percentages of terrestrial OM (< 12%) in the northern part of the ECSS, which may be a reflection of the intrusion pathway of the outer seawater.
