This study analyzed a time series data of daily subPSI values to determine the temporal and spatial characteristics of ambient air-quality in Taiwan by employing the Varimax rotational method. The first and second rotational principal components nearly accounted for 54 and 19% for the variation of subPSI values over Taiwan. The factor loadings between rotational principal components and subPSI values of air pollutants identified the first and second components as combustion and photochemical sources, respectively. Time series analysis of rotational component scores associated with regions showed the relationships between rotational components and subPSI values and also revealed the optimum simulation period for combustion and photochemical sources.
本研究分析了每日次PSI值的时间序列数据，采用方差最大化旋转法来确定台湾地区环境空气质量的时空特征。前两个旋转主成分分别解释了台湾地区次PSI值变化的约54%和19%。旋转主成分与空气污染物次PSI值之间的因子载荷分别将第一和第二成分确定为燃烧源和光化学源。与各区域相关的旋转成分得分的时间序列分析显示了旋转成分与次PSI值之间的关系，还揭示了燃烧源和光化学源的最佳模拟期。
