摘要
根据１９９０ 年春季和秋季２ 个航次对涠洲岛附近海域的水质和底质监测结果， 采用指数法公式对涠洲岛周边海域的水质与底质的基本情况进行分析和评价， 结果是涠洲岛附近海域的ｐＨ值、溶解氧和ＣＯＤ等各值的分布均匀， 水质较好； 油类和重金属的含量均低于一类海水标准， 无超标现象，
The seawaters and sediments quality at the sea area around Weizhou Island was monitored in two voyages in spring and autumn 1990 respectively.Using the formula of index method,the basic condition of the seawaters and sediments were analysed and evaluated.The results showed that the values of pH,DO and COD were well distributed.The quality of seawaters was fairly good.The contents of oils and heavy metals were all lower than that of the standard of first grade seawaters.And the sediment environment was not polluted either.
