【Abstract】 The coupling transformation relationships among Fe, Mn and P in a low turbidity reservoir were studied by means of site -monitoring and data correlation analysis. The results indicate that the concentrations of Fe and Mn and P as well will increase in a large scale when thermocline layer and anaerobic layer formed in the reservoir in summer. Concentrations of Fe, Mn and TP in the hypolimnion were 12.7, 16.3 and 3.4 times greater than those in the epilimnion respectively. Correlation analysis clearly demonstrated that there are evident coupling relationships amount Fe, Mn and P transformation. A concept model of iron, manganese and phosphorous transformation in this reservoir has been established.更多还原
