英文摘要	The surface samples were collected from Liaodong Bay in August 2014. Total organic carbon (TOC), total nitrogen (TN), carbon and nitrogen isotopes were measured to analyze the characteristics and sources of organic matter. The results showed that TOC in surface sediments of Liaodong Bay ranged from 0.23% to 1.76%, with an average of 0.72%; TN ranged from 0.02% to 0.09%, with an average of 0.04%. The delta~(13)C values ranged from-23.89 to-21.82 and the average of them was-22.34. The delta~(15)N values ranged from 5.27 to 9.68 and the average of them was 7.43. Compared with particle size, human factors have a greater impact on delta~(13)C and delta~(15)N. The organic pollution assessment showed that the southwest and northeast of Liaodong Bay are polluted to some extent. Calculated by the classical binary mode, the proportion of marine organic matter ranged from 51.77% to 86.31% and the average of them was 77.66%. Therefore, the input source of organic matter in Liaodong Bay is mainly marine organic matter, and the source of terrestrial organic matter is mainly C3 plants. The results provide a scientific basis for the overall planning of ecological protection and restoration and regional pollution control in the Bohai Sea, and provide a powerful data reference for action plan for comprehensive management of Bohai Sea.
