春季青岛鳌山湾沿岸海水水质状况分析与评价

Assessment on the water quality of coastal seawater in the Aoshan bay, Qingdao in spring

  • 摘要: 本文根据2019年春季的调查资料,运用污染指数评价法对鳌山湾沿岸的海水环境质量进行评价,分别使用相对和绝对限制法确定营养盐限制因子,采用营养状态质量指数法和富营养化指数法评价其营养现状,并分析化学需氧量与浊度的相关性。结果表明:(1)春季鳌山湾沿岸海水属Ⅰ类水质,化学需氧量、溶解无机氮和溶解无机磷污染程度较低;(2)鳌山湾沿岸海水出现硅限制和磷限制现象,无氮限制现象;(3)鳌山湾沿岸未出现富营养化现象;(4)鳌山湾沿岸海水的化学需氧量与浊度呈显著正相关性。

     

    Abstract: Based on the investigated data in spring 2019, the water quality of the coastal seawater in the Aoshan bay was evaluated by the pollution index. Nutrient limitation factors were determined by both the relative and absolute limiting principle methods, and nutritive status was assessed with both the nutrient state quality index and eutrophication index. The correlation between chemical oxygen demand (COD) and turbidity was analyzed. The results showed that: (1) The coastal seawater of the Aoshan bay was of good quality in spring, with low pollution in COD, dissolved inorganic nitrogen and dissolved inorganic phosphorus; (2) There existed silicon and phosphorus limitations but no nitrogen limitation; (3) There was no eutrophication situation; (4) COD and turbidity presented a significant positive correlation.
