| 摘要: |
| [目的]调查及评价钦州湾近岸海域夏季海水富营养化水平状况。[方法]2010年6月采集钦州湾近岸海域15个站位的海水样品,测定海水中化学需氧量(COD)、无机氮(DIN)、活性磷酸盐(PO4-P)等的浓度;采用单因子污染指数法对污染程度进行评价,采用海水富营养化指数法以及潜在富营养化程度评价模式对海水富营养化水平进行评价。[结果]钦州湾近岸海域夏季海水中COD平均浓度为1.00mg/L,DIN平均浓度为0.12mg/L、PO4-P平均浓度为0.01mg/L。单因子污染指数法评价结果显示,钦州湾近岸海域海水中COD浓度符合国家一类海水水质标准;DIN浓度超标率为20%;PO4-P浓度超标率为20%。海水富营养化指数法评价结果显示,钦州湾海域海水富营养化指数平均值为0.47;海水潜在富营养化程度评价模式评价结果显示,钦州湾海域海水营养级别为Ⅱ级。[结论]钦州湾近岸海域海水受无机氮及活性磷酸盐污染;海水富营养化水平为贫营养;钦州湾近岸海域海水富营养化程度主要受陆源污染物及海水养殖影响。 |

| Abstract: |
| [Objective] The survey and assessment on the eutrophication level of Qinzhou bay coastal waters were conducted.[Methods] 15 sea water samples were collected by Guangxi Qinzhou Bay in June 2010.The concentration of COD,DIN and PO4-P were determined.The pollution status of sea water was assessed by the index technique of single factor.The eutrophication level of sea water was assessed by the method of eutrophication index and potential eutrophication assessment model.[Results] The mean concentration of COD,DIN and PO4-P of Qinzhou bay coastal waters were 1.00mg/L,0.12mg/L,and 0.012mg/L, respectively.The mean concentration of COD was meet the national sea water quality standard of the first category.The over standard rate of the mean concentration of DIN and PO4-P was 20%.The mean eutrophication index of Qinzhou bay coastal waters was 0.47.The eutrophication grade of Qinzhou bay coast was Ⅱdegree.[Conclusion] The sea water of Qinzhou bay coast was polluted by DIN and PO4-P.The eutrophication level of Qinzhou bay coast was pool nutrient.The eutrophication degree of Qinzhou bay coast was mainly affected by the land-source pollutant and mariculture. |
