| 摘 要： | 依据2004年的调查资料与历史资料对比,分析了罗源湾海区多年来水质、水域的养殖力(营养盐、叶绿素a和初级生产力)以及浮游植物多样性的变化,并采用潜在生态危害指数法对其生态危害程度进行评价.结果表明,罗源湾水体中的无机氮和活性磷酸盐超过二类水质标准,沉积物中除Hg、Cd污染较为严重外,其它重金属的生态危害很小.此外,还对罗源湾表层沉积物微量元素进行了调查研究.

| Abstract: | This paper analyzes the change of water quality,aquatic culture force and phytoplankton diversity in the sea area of the Luoyuan Bay over the past few years according to the contrast between the data obtained in the 2004 investigation and in history,and evaluates the potential ecological index of harmfulness and its degree. The result shows that the contents of nitrogen and active phosphate in some water area of the Luoyuan Bay are not up to the first standard water quality,but the ecological harm of heavy metals in sediment is slight except for the serious pollution of Hg and Cd. |
