| 摘 要： | 根据1998—2002年对古镇口港海域5期的监测结果，初步探讨了该海域环境因子的变化特征和营养水平。结果表明：该海域水质较好，除油类和CODMn外，1998年达到GB 3097—1997第一类海水水质标准，1999年水质超过第四类标准，2000，2001年水质达到第三类标准，2002年达到第二类标准。其中无机氮和活性磷酸盐含量近年略有上升，氮磷比平均为26．8。富营养化指数平均为37．2，并呈迅速下降态势，已从1999年的137降为2002年的0．733。但该水域受油类和CODMn污染较严重，CODMn的含量从1999年开始连续3年超过第四类海水水质标准，2002年明显好转，达到第一类海水水质标准；油类的含量连续5a达到第三类海水水质标准。综合来看，古镇口港海域水质目前状况较好。 |

| Abstract: | Based on the monitoring results of Guzhenkou Port sea area from 1998 to 2002, a preliminary discussion on the variabilities of environmental factors and the nutrient level of the sea area was made. It is shown from the monitoring results that the water quality except oils and COD Mn of the sea area was comparatively good, the water quality in 1998 achieved the standards for seawater quality of first category (GB 3097 1977), that in 1999 was in excess of the standards for that of fourth category, those in 2000 and 2001 achieved the standards for that of third category, and that in 2002 achieved the standards of second category. Among them, the contents of dissolved inorganic nitrogen and reactive phosphate increased slightly in recent years and the mean ratio of N to P was 26.8; the mean eutrophication index was 37.2 and the index decreased drastically from 137 in 1999 to 0.733 in 2002. However, the sea area was seriously contaminated by oils and COD Mn , the contents of COD Mn were in excess of the standards for seawater quality of fourth category from 1999 to 2001, and that in 2002 was reduced obviously to achieve the standards for that of first category; the contents of oils achieved the standards for that of third category from 1998 to 2002. In summary, the seawater quality in the sea area is comparatively good at present. |
