摘要
文中利用因子分析法对大连湾的水质污染进行了评价研究,从众多监测项目中提取具有代表性的五个主要因子,通过对各个因子所关联的监测项目的分析,对其所代表信息进行了科学定义。利用kriging插值法归纳了各因子的空间分布及季节变化规律。
The Factor analysis was used in the assessment of seawater quality along DaLian bay. Five main pollutants, those were considered to reflect the water qualities of mentioned water area, were selected, further based on chemical analysis of related water samples respective data were defined, and then by means of kriging interpolation method the spatial distribution and seasonally changing orderliness of the mentioned factors were investigated,
