| Abstract: | This paper used principal component analysis to estimate the water quality in Yangtze River and get the sequence result of the polluting strength in 17 areas.We set up a stable mathematical model of water quality.By this model,we determined the changes on the main stream,and get the source which produces the main pollutant permanganate and the ammonia nitrogen.Compared with reality conditions,the research has certain reliable and practical significance. |
