根据2007年4个航次(1月、4月、7月和11月)的调查资料,分析了营养盐、pH、盐度、DO、COD和叶绿素a的季节变化特征,并进行水质富营养化评价及有机污染评价。结果表明:象山港海域不同季节N/P变化不大并受磷限制;氮磷含量丰富,全年处于严重富营养化状态;有机污染评价的结果显示,象山港海域春夏季为中度污染,秋冬季为严重污染。
According to the survey data of 4 voyages in 2007 (January, April, July and November), the seasonal variations of nutrients, pH, salinity, DO, COD and chlorophyll a were analyzed and the eutrophication Evaluation and organic pollution evaluation. The results showed that the N / P of Xiangshan Port in different seasons did not change much and was limited by phosphorus; the content of nitrogen and phosphorus was abundant and it was in a severe eutrophication state throughout the year. The results of organic pollution evaluation showed that the spring and summer of Xiangshan Harbor were moderately polluted, Autumn and winter as a serious pollution.
