| 英文摘要 | Samples of total suspended particulate matter(TSM)from inflow rivers of the Bohai Sea and the North Yellow Sea over different seasons were collected and analyzed for concentrations of total organic carbon(POC), total nitrogen(PN), and stable isotopic composition(delta~(13)C and delta~(15)N). These isotopic compositions were used for identifying the sources of organic carbon and nitrogen in suspended particulate matter. The results showed that the seasonal variation of delta~(13)C and delta~(15)N in TSM were delta~(13)C_(medium flow)>delta~(13)C_(high flow)>delta~(13)C_(low flow) and delta~(15)N_(high flow)>delta~(15)N_(medium flow)> delta~(15)N_(low flow), respectively. The sources of total suspended particulate organic matter suggested obvious seasonal variations in river inflows. The C3 plant, soil organic matter, and macrophyte were the main mixture sources of organic matter during medium flow(spring and autumn). The contribution of phytoplankton increased during high flow(summer). The suspended organic matter was derived mainly from mixture sources of C3 plant debris and autochthonous organic matter during low flow(winter); sources of suspended particulate nitrogen mainly included seasonal precipitation, municipal sewage, fertilizer, and autochthonous macrophyte. |
