| Abstract: | Mianyuan River plays an important role in economic development of Deyang.Bajiao cross section is at the exit of the river functional zone.For the first time,this paper analyzed and evaluated the status quo and future trend of the water quality at Bajiao cross section using the methods of Spearman rank correlation coefficient and the grey model GM(1,1) trend factor alpha respectively.It concluded that the NH3-N was the reality pollution factor.The causes of pollution were discussed as well.It proposed that t... |
