摘要
因子分析法是主成份分析方法的推广和深化,是把原来多个变量化为少数几个综合指标的一种统计方法。本文通过该法对江安河四川大学双流校区段水质进行了评价,结果表明,该水体受到了不同程度的有机物污染,其中非离子氨、阴离子洗涤剂、化学耗氧量,溶解氧所占的负荷最大。
Factor analysis is, an extent to principal component analysis, a statistical method that uses several factors to represent many original factors. In this paper using this method the water quality of Jiangan River in the Shuangliu campus of Sichuan University is evaluated. Result shows organic matters, such as non-ionic ammonia, anionic detergent, COD and BOD, have polluted the river mainly.
