| 摘 要： | 自20世纪90年代以来,天津海域赤潮频发,水质不断恶化.为研究水质年变化情况,于2006年对天津海域进行监测.采用基于因子分析的主成分分析方法,将水质参教概括为7个主成分,并分析各个主成分的含义以及各水期变化规律.最后结合空间数据,分析了7个主成分年均值的空间分布特征和意义.结果表明,首要污染因子是营养盐,污染类型分为2种.

| Abstract: | By use of the principal component analysis method based on factor analysis,seven principal components were extracted from the water quality parameters.The significance of the seven principal component and the variation of three period averaged were studied.Finally,integrating the water quality monitoring data and the spatial data,the implications of the seven principal components and their spatialed distribution characteristics were analyzed.The results showed that chiefly contaminations were alimentation s... |
