| 摘要: |
| 根据2006 年6 月和2007 年6 月两次对胶州湾大沽河河口邻近海域表层海水的温度、盐度、pH、悬浮物(SS)、溶解氧(DO)、化学需氧量(COD)、亚硝酸盐(NO-2-N)、硝酸盐(NO-3-N)、铵氮(NH+4-N)、活性磷酸盐( PO-34-P)、铜、铅、锌、镉、石油类等理化指标测定结果, 应用单因子污染指数和富营养化指数对该海域的水质进行了分析和评价。结果显示, 无机氮和石油类为该海域的主要污染物, 该海域总体营养水平较高, 2006 年为磷限制中度营养区域, 2007 年为磷中等限制潜在性营养化区域。 |

| Abstract: |
| The survey of surface seawater quality at the Dagu river estuary and adjacent sea area was conducted in Junes, 2006 and 2007, in which temperature, pH value, salt degree, DO, COD, NH3-N, NO2-N,NO3-N, PO4-P, Cu, Pb, Zn, Cd and oils were measured. The sea water quality was assessed by analysing thesingle pollution index and the nutrient status index. The main pollutants were inorganic nitrogen and oils. Thenutrient level was relatively high at Dagu river estuary and adjacent sea area. It belonged to a phosphorus-limiting sub-eutrophication status in 2006 and 2007. |
