摘要: Changes of the concentrations CODMn, BOD5 and NH3-N from main sections middle upper reaches East River were identified, by using method seasonal Kendall test for water quality data Longchuan, Heyuan Boluo monitoring stations during 2001-2007. The results suggest that: (1) increase significantly at all stations; (2) CODMn do not display a significant trend Longchuan control section, showed decreasing an increasing both sections; (3) change in rate is larger than that reaches; (4) mainly influenced waste discharge.
