Through twice sampling collections of eight sections of Weihe River in April and September, 2015, the distribution feature of the pollutants in surface sediment pore water and overlying water was analyzed, the correlation between the concentrations of the pollutants in surface sediment pore water and that in overlying water was conducted. the results showed that, the concentrations of TN, NO3-N, NH3-N and COD in the overlying water of the wet period were all higher than those of the level period, of which D5 (before Jinghe River flows into Weihe River) had high concentrations of pollutants. The concentrations of TN, NH3 - N and NO3 -N in pore water had similar change trend, TN, NH3 - N and NO3 -N of wet period were higher than those of the level period, TP and COD had high contents in D5 and D7(after Jinghe River flows into Weihe River) for the wet period. The correlation analysis showed that, the TN, TP and COD concentrations in surface sediment interstitial water were significantly correlated with the TN, TP and COD concentrations in overlying water in the level period, and were highly correlated in the wet period, which indicated that the concentrations of TN,TP and COD in pore water determinants the concentrations of TN,TP and COD in the overlying water.
