摘　　要：富营养化水体中最常见的微囊藻毒素对人类的健康产生了重大威胁。文章总结了微囊藻毒素在我国湖泊中的分布情况、季节变化,介绍了微囊藻毒素与营养盐、叶绿素、藻细胞密度、光照、水温等理化因子之间的关系,并分析其分布、季节变化以及与理化因子之间关系结论不一致的原因,进一步提出通过控制环境因素来控制微囊藻毒素的浓度,并将叶绿素a作为微囊藻毒素和富营养指标的一个纽带来确定营养物标准。Microcystins,which is common seen in eutrophication water,has very great threaten to human's health. This paper summarizes the distributions and the season changes of Microcystins in lakes all over China. It is introduced that the relationships between Microcystins with physicochemical factors including nutrition,chlorophylla,algae cell density,light and water temperature. The differences of these relationships are analyzed and a method is also proposed to control the concentration of mircrocystins by the means of controlling the environmental factors. The chlorophyll a is used as a link combining the microcystins and eutrophic index in order to establish a nutrient standard, and further to provide protection for human health.
