摘要
根据2008年6～10月3个航次的监测,阐述了广西防城港市珍珠湾海域营养盐的变化特征,对其PO4-P、SiO3-Si、DIN、pH值、盐度、DO、COD和叶绿素a等进行了分析,并对该海域进行了富营养化评价及有机污染评价。结果表明,该海域营养盐随月份呈现不同的变化规律。从营养结构看,与Redfield值比较,符合P限制条件。根据富营养化评价,珍珠湾海域属贫营养水平。有机污染评价的结果显示,珍珠湾海域属于水质开始受污染类型。
According to the three monitoring from June to October in 2008, the variation characteristics of nutrient at Zhenzhu Bay were discussed, as well as PO4- P, SiO3-Si, DIN, pH value, salinity, DO, COD and Chlorophyll a. At the same time , Eutrophication Assessment and organic pollution evaluation about this Sea Area also were performed. The results showed that the nutrient changed monthly. Comparing to Redfield value in trophic structure, it accorded with P limiting condition. According to Eutrophication Assessment, it belonged to pool nutrient status, and the organic pollution evaluation showed this sea area belonged to beginning suffer pollution types.
