摘要
采用主成分分析法对清河门地区的水质进行了综合评价,确定出清河门地区的水质指标间的相关关系.分析结果表明,对于观测数据重叠、高维空间分布复杂的情形,主成分分析法是一种切实可行的方法.
This paper applies the principal ingredient analysis method to the appraisement of the water quality in Qinghemen area. The correlation between different indexes of water quality is confirmed. The findings indicate that the principal ingredient analysis method is feasible while observing the overlapped data and the complex spatial distribution.
