          2.1 海水質量

          福建大部分海域海水符合清潔、較清潔海域海水水質標準,海水水質狀況基本良好。近岸海域海水中石油類、無機氮、活性磷酸鹽不同程度超標,部分海域中度污染或嚴重污染(見圖1),遠海、近海海水水質優于近岸。三沙灣、三都澳、閩江口、福清灣、興化灣、泉州灣、廈門海域、東山灣、詔安灣局部海域海水中石油類含量超標;閩江口近岸海域海水中汞含量超標;廈門海域、泉州灣、三都灣、閩江口海域海水中無機氮含量超標;三都灣、廈門海域海水中活性磷酸鹽含量超標。

          The water quality in Fujian’s most sea areas was good on the whole, reaching the standard of “Clean” or “Less Clean”. Petroleum, inorganic nitrogen, activated phosphate in the offshore marine areas exceeded the standard to different extents. Parts of marine areas were medium polluted or seriously polluted (see Fig. 1) and the water quality of open and offing sea areas excelled that of the offshore marine areas. Petroleum concentration in Sansha Gulf, Sandu’ao Gulf, the Min River Estuary, Fuqin Gulf, Xinhua Gulf, Quanzhou Gulf, Xiamen’s marine areas, Dongshan Gulf and parts of Zhao’an Gulf exceeded the standard. Hydrargyrum concentration in the offshore marine areas, inorganic nitrogen concentration in the marine areas of Xiamen, Quanzhou Gulf, Sandu’ao Gulf and the Min River Estuary, and activated phosphate concentration in the Sandu Gulf and Xiamen’s marine areas exceeded the standard respectively.

          清潔海域:符合國家海水水質標準中一類海水水質的海域,適用于海洋漁業水域,海上自然保護區和珍稀瀕危海洋生物保護區。
          較清潔海域:符合國家海水水質標準中二類海水水質的海域,適用于水產養殖區、海水浴場、人體直接接觸海水的海上運動或娛樂區,以及與人類食用直接有關的工業用水區。
          輕度污染海域:符合國家海水水質標準中三類海水水質的海域,適用于一般工業用水區。
          中度污染海域:符合國家海水水質標準中四類海水水質的海域,僅適用于海洋港口水域和海洋開發作業區。
          嚴重污染海域:劣于國家海水水質標準中四類海水水質的海域。

          Clean Marine Areas: Reach the standard of GradeⅠ of < Quality Standard for State Oceanic Water >. Suitable for marine fish culture, marine nature reserves and marine endangering life protection zones.
          Less Clean Marine Areas: Reach the standard of GradeⅡ of < Quality Standard for State Oceanic Water Standard>. Suitable for aquiculture, marine bathing places, marine sports in which people could get in direct touch with the water or recreation places as well as the water used for human grocery industry.
          Lightly Polluted Marine Areas: Reach the standard of Grade Ⅲ of < Quality Standard for State Oceanic Water >. yes"> Suitable for ordinary industrial parks using water
          Medium-polluetd Marine Areas: Reach the standard of GradeⅣ of < Quality Standard for State Oceanic Water >. Only suitable for marine port water and marine developmental areas.
          Seriously Polluted Marine Areas: Worse than the standard of Grade Ⅳ of < Quality Standard for State Oceanic Water >.

          近岸海域海水污染范圍有所擴大。與2002年相比,清潔、較清潔海水分布范圍從56.41%下降到48.84%;輕度污染范圍從28.21%上升到30.23%;中度污染范圍從5.13%上升到6.98%;嚴重污染范圍從10.25%上升到13.95%。

          The ranges of polluted offshore marine areas have somewhat expanded. Compared with 2002, clean and less clean marine areas decreased from 56.41% to 48.84%; lightly polluted ranges increased from 28.21% to 30.23%; medium-polluted areas increased from 5.13% to 6.98% and seriously polluted areas from 10.25% to 13.95%.
