摘　　要：对艾溪湖沉积物柱样中叶绿素、胡萝卜素、颤藻黄素、蓝藻叶黄素等色素进行了提取,用紫外可见分光光度法进行测定,根据各色素所代表的环境意义,揭示了艾溪湖300多年来的环境变化等特征。结果表明,近几十年来,艾溪湖一直处于富营养化状态,湖泊正在萎缩,其富营养化态势与该地区20世纪50年代后的一系列人类活动密切相关。Several pigments in Aixi Lake including chlorophyll, carotenoids, oscillaxanthin and myxoxantho-phyll are extracted and tested, and their contents in lake sediments are calculated. The evolution of Aixi Lake＇s environment is discovered by means of the environmental meaning that every pigment stands for. The results show that Aixi Lake becomes seriously eutrophic, it is in shrinking stage for several decades, which is tied up with many human activities of this region since 1950 s.
