| 摘 要： | 根据2006年3月和7月的调查数据,对天津港南部海区海水的营养水平及动态变化进行了评价。考虑到水质状况和水体营养水平是水体中多项指标分析评价的综合结果.本文先通过单项指标评价法和营养指数法进行评价。然后又通过集对分析方法,选择化学需氧量(COD)、无机磷(DIP)、无机氮(DIN)、叶绿素a(Ch1—a)等作为评价指标,对该区海水富营养化水平进行了综合评价。评价结果表明集对分析方法更能反映海水的实际富营养化状况,计算结果显示天津港南部海域两期调查中除21,26.27和29站位在7月呈富营养化状态其余站位海水均在中营养(Ⅳ)及以下水平状况,未达到富营养化水平,水质状况较好。

| Abstract: | On the base of the measurement in the aquatic environments in the south sea in March and July,2006,the assessment and classification of water quality and nutrient level in south sea of Tianjin harbor has been studied.By the set pair analysis model,COD,T-N, phosphate and Chl-a were chosen to be the assessment parameters for the eutrophication of seawater.The results showed that this method could bring less errors compared with others. However,more appropriate method should further be developed for water environmental pollution in the future.The computed result showed that in the two issues of investigations except 21,26,27 and 29 stations positions in July have become eutrophic,but in other posi- tions seawater were medium-eutrophic(IV)even lower.The water quality condition was better totally. |
