摘　　要：于2020年5—11月,对莱州湾和四十里湾贝类养殖海域营养盐含量以及相关环境因子进行调查,采用营养指数法、有机污染指数法、单因子评价指数法以及内梅罗环境质量综合评价指数法,对2处水质状况进行分析与评价。结果表明,莱州湾和四十里湾贝类养殖海域中ρ(无机氮)分别为0.056~0.277 mg/L、0.047~0.143 mg/L,ρ(活性磷)分别为0.007~0.012 mg/L、0.002~0.019 mg/L,ρ(总磷)分别为0.010~0.057 mg/L、0.008~0.032 mg/L,个别点位的无机氮和总磷超标,其余点位均符合《海水水质标准》(GB 3097—1997)二类水质标准;温度分别为13.4~28.3℃、13.6~24.8℃,盐度分别为2.72%~3.14%、2.92%~3.22%,pH值分别为8.0~8.4、7.9~8.3,ρ(溶解氧)分别为5.51~9.34 mg/L、5.65~8.78 mg/L,ρ(化学需氧量)分别为0.44~1.92 mg/L、0.32~2.04 mg/L,均符合《海水水质标准》(GB 3097—1997)二类水质标准;2处海域以贫营养水平和中营养水平为主,未受到有机污染,水体基本清洁。指出,莱州湾和四十里湾贝类养殖海域营养盐含量及其他环境因子处于合理范围,适宜贝类养殖。This study explored nutrient content and related environmental factors in the shellfish aquaculture areas of Laizhou Bay and Sishili Bay from May to November in 2020.Nutrition Index method,Organic Pollution Index method,Single Factor Evaluation Index method and Nemerow Environmental Quality Comprehensive Evaluation Index method were used to analyze and evaluate the water quality of the two sites.The results showed that,in Laizhou Bay and Sishili Bay,inorganic nitrogen were 0.056-0.277 mg/L and 0.047-0.143 mg/L,active phosphorus were 0.007-0.012 mg/L and 0.002-0.019 mg/L,total phosphorus were 0.010-0.057 mg/L and 0.008-0.032 mg/L.Although the inorganic nitrogen and total phosphorus in some sites exceeded the standards,the other sites all met the national Class II water quality standards of standards for seawater quality(GB 3097—1997).The temperature were 13.4-28.3℃and 13.6-24.8℃,salinity were 2.72%-3.14%and 2.92%-3.22%,pH were 8.0-8.4 and 7.9-8.3,dissolved oxygen were 5.51-9.34 mg/L and 5.65-8.78 mg/L,chemical oxygen demand values were 0.44-1.92 mg/L and 0.32-2.04 mg/L,which met the national Class II water quality standards of standards for seawater quality(GB 3097—1997).The nutrient levels in the two sites were mainly poor and medium,and were not in organic pollution,basically the water quality is clean.It was pointed out that the nutrient content and other environmental factors in the shellfish aquaculture areas of Laizhou Bay and Sishili Bay were in a reasonable range,which is suitable for shellfish culture.
