中文摘要：

考虑到常用水质富营养化评价模型的单一、确定性缺点,尝试将动态聚类分析与盲数耦合理论引入水环境富营养化评价领域,建立了改进的综合营养状态指数评价模型,最后借助克里格插值法对评价结果的可信度进行空间可视化表征。利用改进模型对2009年洞庭湖区域的水环境空间的富营养化状况进行了评价,结果表明,东洞庭湖、扁山、鹿角富营养化程度相对严重,隶属于富营养化的可信度分别达到了0.5444、0.5318和0.5260。与确定性评价模型对比分析表明,所建改进模型更充分地考虑到被观察个体的差异,集成了更全面的样本信息,并可同时计算出了各采样点综合营养状态指数的区间数与其相对应的可信度水平,从而有效地提高了评价模型的可分辨性。
