| 摘 要： | 根据2007年6～9月和2008年6～10月6个航次的监测资料,分析了红沙养殖区海域水质变化特征,并对PO4-P、SiO3-Si、DIN、pH值、盐度、DO、COD和叶绿素a等进行了分析,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,红沙养殖区海域营养指数秋季较低,而夏季较高,属富营养化状态;有机污染评价的结果显示,红沙养殖区海域属于水质开始受污染类型。

| Abstract: | According to the monitoring data of six flight times from June to September in 2007 and June to October in 2008,the variation characteristics of water quality in Hongsha aquaculture area were discussed.PO4-P,SiO3-Si,DIN,pH value,salinity,DO,COD and chlorophyll a were analyzed.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.Compared with the to redfield value in trophic structure,it accorded with P limiting condition.According to eutrophication assessment,nutrient index in summer were higher than in autumn,it belonged to eutrophication,and the organic pollution evaluation showed this area belonged to beginning suffer pollution types. |
