| 摘 要： | 针对湖泊富营养化的评价问题,依据集对分析理论,提出了用联系数来评价湖泊富营养化程度的方法。建立湖泊的水质样本与不同富营养化等级间的联系度表达式,根据水质样本各指标的实测值与各等级标准界限值的关系,确定差异度系数的取值,计算联系数,据此进行湖泊富营养化状态的综合评价。通过对5个湖泊富营养化程度的综合评价和对评价结果的比较分析,说明了该方法的可行性和有效性。

| Abstract: | For issues of lake eutrophication assessment,from the set pair analysis theory,this paper presents the relational number used to evaluate lake eutrophication approach.Namely,establishes the related degree formula between the lake water sample and standards of different eutrophication,determines the coefficient of difference degree based on the relationship between water samples measured values of each index and the level of the threshold,calculates relational number and accordingly carries out a comprehensi... |
