乳山湾东流区海水营养盐消长与盐度的关系

RELATIONSHIP BETWEEN NUTRIENTS AND SALINITY IN RUSHAN BAY

利用数理统计的方法，对乳山湾东流区6～9月间的水化学、水文和生物观测数据进行处理。结果表明，6～9月间硝酸盐与盐度有着极显著的负相关关系，6月和9月亚硝酸盐和氨氮与盐度是显著性相关，而7月和8月养殖高峰期间呈弱相关关系。磷酸盐仅9月与盐度呈显著性负相关。各月调查营养盐的变异系数较大于盐度的变异系数，说明了它们的变化不仅受沿岸水系混合的影响，而且也受到环境污染、生物活动和化学反应等的影响。

Statistical analysis of data on nutrients and salinlty yielded the nutrients vssalinity regtession relationship showed that nitrate in this bey correlated closely with salinity inthe survey periodl that nitrite and ammonia had close corretation with salinity in June andSeptember ;and that Phosphate had closer corretation with salinity in September.
