摘要 根据2013~2015年对沿浦湾浅海养殖区的水质进行的监测与分析资料,采用富营养化指数法和有机污染指数法对该海域海水营养状况和有机污染状况进行了评价.结果表明,该养殖区海水的溶解氧(DO)和化学需氧量(COD)含量符合国家二类海水水质标准,超过二类标准的指标为无机氮(DIN)、活性磷酸盐(PO_4^(3-)-P)和石油类.该养殖区春、冬两季水质指标超标情况较为明显,春季超标指标为无机氮和石油类,冬季超标指标为无机氮和活性磷酸盐.该养殖区的富营养化程度日趋严重,而有机污染程度总体不高. Seawater quality of the mariculture zones in Yanpu Bay was monitored and analyzed from 2013 to 2015.Eutrophication index and organic pollution index were used to evaluate the nutrition state and organic matter pollution of the water in this area. The results indicated that the indices,including DO and COD,satisfied the second class of seawater quality standards,whereas the concentrations of inorganic nitrogen,active phosphate and petroleum exceeded the second class of the standard. The water quality exceeded the standard much severely in winter and spring. The main pollutants beyond the standard in winter were inorganic nitrogen and petroleum,while in springwere inorganic nitrogen and active phosphate. Generally,the organic pollution was not quit serious in this mariculture zone though the eutrophication became severe.
