根据 1 995年 1 0月至 1 996年 7月秦山 期核电站邻近水域生态调查资料 ,对叶绿素 a的分布特征进行研究。结果表明 ,该调查水域叶绿素 a含量低 ,表层叶绿素 a平均含量为 0 .2 93mg/m3,底层叶绿素 a平均含量为 0 .2 2 2 mg/m3。叶绿素 a含量的季节变化明显 ,秋季最高 ,其它依次为夏季、春季、冬季。与该水域过去的调查资料进行比较分析 ,发现叶绿素 a的含量有明显下降。
According to the ecological survey data of Qinshan Period nuclear power station from January 1995 to July 1996, the distribution characteristics of chlorophyll a were studied. The results showed that the contents of chlorophyll a in the waters of the survey were low, the average content of chlorophyll a in the surface waters was 0.233 mg / m3, and the average content of chlorophyll a in the bottom waters was 0.222 mg / m3. The seasonal variation of chlorophyll a content is obvious, the highest in autumn, followed by summer, spring and winter. Compared with the past survey data of this area, it was found that the content of chlorophyll a decreased obviously.
