摘 要:以黄河山东段为例,在利用方差分析(ANOVA)对高村、孙口、艾山、泺口和利津5个断面2015-2017年各水质监测指标月度监测值进行时空尺度显著差异性分析的基础上,采用层次聚类分析法将180个水质样本分成12组,并以各组样本均值为基础,运用综合水质标识指数法对河流综合水质进行评价。结果表明:黄河山东段综合水质状况良好,综合水质类别为Ⅰ类或Ⅱ类;时间上,2015-2017年综合水质状况逐渐好转;空间上,利津断面综合水质状况最差,其余断面从上游到下游综合水质状况呈好转趋势。The Shandong reach of the Yellow River was measured as the research area in this study. Based on the results of analyzing the temporal and spatial differences of monthly surveillance data of five monitoring sites from 2015 to 2017 according to the analysis of variance(ANOVA), 180 samples were divided into 12 groups by hierarchical cluster analysis. Using the sample mean of each group as the input, the comprehensive water quality identification index of each group was calculated. The results show that the comprehensive water quality of the Shandong reach of the Yellow River is in good condition and the comprehensive water quality of the sampling sections is at class I to class Ⅱ levels. The comprehensive water quality condition has an upwarding trend from 2015 to 2017. The comprehensive water quality of Lijin section is the worst among five monitoring sites and from upstream to downstream, the comprehensive water quality has an upwarding trend except Lijin section.
