摘要
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。
Chlorophyll \%a\% concentration was studied during the ecological investigation in the waters adjacent the 3rd.stage project of Qinshan Nuclear Power Station from October 1995 to July 1996. The surface average chlorophyll \%a\% in the studied is 0 293 mg/m\+3 and 0 222 mg/m\+3 near bottom. There is an obvious seasonal variation in the chlorophyll \%a\% values which appeared in the following order: autumn>summer>spring>winter. Chlorophyll \%a\% concentration decreased sharply during 1995~1996 as compared with 1989~1990
