| 摘 要： | 将主成分分析法运用到水源地水质评价中,对工程实例中5个监测断面的包括高锰酸盐指数、化学需氧量COD、五日生化需氧量BOD5、氨氮、石油类以及大肠菌群等6项水质指标进行分析计算,从信息量的角度讨论了水源地水质各污染组分包含的信息大小及各污染组分对断面水质的影响程度。结果表明,运用主成分分析法处理可以产生新的指标,而新的指标彼此间互补相关,可以很好地反映水质的综合状况。

| Abstract: | The main component analytical method was adopted to evaluate the water source quality. Six items of water quality indexes,such as permanganate index,COD,BOD5,ammonia nitrogen,petroleum and Coliforms were analyzed and calculated in five monitoring sections of the engineering case. The data of each index of water source quality and the influence of each index on section quality were discussed based on the data quantity. The results indicated that it could produce new indexes adopting the main component analytical method,and the new indexes were complementary. It could satisfied reflect the comprehensive condition of water quality. |
