对应分析方法在环境污染中的应用

The Application of Correspondence Analysis in Environmental Pollution

以我国山区某大型化工厂厂区及邻近地区挑选的有代表性的8个大气取样点为样本,先利用对应分析方法对各样本点及大气污染气体进行分类,再利用因子分析的方法对数据进行分析并对比之前的数据处理结果,表明对应分析方法较因子分析方法能得到更好的结果.

Eight representative points which located the regions of a large chemical factory in a mountain and the area around it were sampled.The samples and polluting gases were sorted using the method of correspondence analysis.The data was processed by the method of factor analysis,and then compared with that gotten before.The result shows that the superiority of the correspondence analysis is ahead of the factor analysis.
