摘要
根据2005—2010年海州湾近岸海域的水质监测,通过对11个站位pH值、溶解氧、COD、活性磷酸盐、无机氮和石油类的检测,对该区域的水质状况和趋势作出分析和评价。结果表明:影响该海域水质的主要污染因子是无机氮,部分站位出现磷酸盐、石油类超标。近岸海域的主要污染物略呈上升的趋势,但总体变化基本稳定。
Based on the monitoring results of water quality in offshore water of the Haizhou bay in 2005- 2010, chose pH, DO, COD, PO4-P, DIN and petroleum as assessing indexes. The assessment on the quality and the trend of waters in the region was done. The results indicated that： The main pollutant was DIN, the con- tents of PO4-P and petroleum exceed the standard in some of monitoring site,the pollution in the region showed a upward tendency by years. But the change of the tendency was not obvious.
