舟山电厂附近海域水体中叶绿素a含量的探讨

The discussion Discussion of content Content of chlorophyll Chlorophyll a in the waters Waters near Near Zhoushan Power Plant

对舟山电厂附近海域进行叶绿素a含量的初步调查,并对这该海区叶绿素a含量的变化进行分析,还探讨了叶绿素a含量的分布,以及与环境因子之间的相互关系。调查结果表明,舟山电厂附近海域5、12月两个月叶绿素a含量平均值为1.837μg/L,其中高潮时为1.482μg/L,低潮时为2.193μg/L。分析结果表明,整个调查海区,叶绿素a的含量与海区盐度、水温、光照、气温、透明度等因素密切相关,与高低潮的变化有关。舟山电厂附近海域叶绿素a含量结果表明舟山电厂附近海域水体水质状况良好,未发生水体富营养化。

The contents of chlorophyll a of the waters near Zhoushan Power Plant was investigated, and the content variation of chlorophyll a in this sea area was analysedanalyzed. Furthermore, the content distribution of chlorophyll a, and its interrelation with environmental factors were also discussed. The investigation results showed that the average content of chlorophyll a in the waters near Zhoushan Power Plant in May and December was 1. 837 μg/L, and the average contents of chlorophyll a were 1. 482 and 2. 193 μg/L at high tide and at low tide, respectively. The analysis showed that the content of chlorophyll a was closely related to salinity, water temperature, light, air temperature, and transparency, and had a correlation with change between high tide and low tide. The contents of chlorophyll a of the waters near Zhoushan Power Plant indicated that the water quality was satisfactory and there was no water eutrophication in this sea area.
