2、硝酸盐、总磷和化学需氧量的含量均高于亚龙湾,且个别月份间呈显著性差异(P<0.05)和极显著性差异(P<0.01);对水体中pH值和溶解氧的测定表明,2处海湾水体符合国家I~Ⅱ类海水水质标准:三亚湾和亚龙湾水体中的磷酸盐浓度分别为0.0152~0.0189mg/L和0.0082~0.0143mg/L.分别符合国家Ⅱ~Ⅲ类和I类海水水质标准;化学需氧量含量分别为0.528~0.899mg/L和0.533~1.013mg/L,均符合国家I类海水水质标准。亚龙湾水体水质优于三亚湾,且前者多数海域水体符合国家
3、I类海水水质标准:后者多数海域符合国家Ⅱ~Ⅲ类水质标准,少数符合国家I类水质标准。关键词:三亚湾;亚龙湾;水质;海水水质标准;三亚市中图分类号:X824文献标识码:A文章顺序编号:1672—5190(2014)07—0003—05EvaluationandComparisonofWaterQualityofSanyaBayLIYou—ming,WANGPing2,LIYi-jun,LIXiao—mei,CHENMin,CHENHou-shou,GUOZheng—yan(1.BiologicalScie
