应用季节性Kendall检验法分析滦河水质变化趋势，并进行污染源识别。结果表明：滦河干流CODMn和NH3-N 2个指标的浓度、污染物输送率及流量调节浓度均没有明显变化；通过流量调节后上下游各站点浓度变化趋势趋于一致，同一站点CODMn和NH3-N的变化趋势也较一致，流量调节浓度趋势分析能够更好地反映水质变化趋势。5个监测站点中只有三道河子和乌龙矶2个断面的CODMn浓度出现小幅上升；5个监测站点NH3-N输送率均未出现上升趋势，三道河子、乌龙矶和滦县3个监测站点CODMn输送率呈现上升趋势。郭家屯监测站点以上CODMn和NH3-N主要受面源污染影响；郭家屯以下的4个监测站点受点源和面源污染的双重影响，以点源为主。总体上，滦河干流水质有所好转，污染源中含氮有机物浓度在不断降低或稳定不变，有机污染物总量呈增长趋势。指出郭家屯监测站点以上要积极推进水土保持工作，减少水土流失造成的面源污染；滦河下游要加强对点源污染的治理。

The seasonal Kendall test method was used to analyze the change trend of water quality in the Luanhe River and identify the pollution source .The results show that the concentrations , pollutant transport rates , and flow control concentrations of COD Mn and NH3-N do not display a significant change trend in the main stream of the Luanhe River .The change trends of concentrations upstream and downstream of the sites were consistent , and the same-site CODMn and NH3-N change trends were also consistent after flow control .Flow control concentration analysis can better reflect the change trend of water quality .Of the five monitoring stations , two stations , the Sandaohezi and Wulongji stations ,had a slightly rising trend in COD Mn concentration .The NH3-N transport rate showed no rising trend at any of the five monitoring stations .The CODMn transport rate showed a rising trend at the Sandaohezi , Wulongji, and Luanxian stations .CODMn and NH3-N above the Guojiatun Station were mainly affected by non-point source pollution.CODMn and NH3-N at the other four stations were affected by both point source pollution and non -point source pollution , with the point source pollution being dominant .As a whole , the water quality in the main stream of the Luanhe River has improved , the concentration of nitrogen organic matter in the pollution source is decreasing or remains unchanged , and the total amount of organic pollutant shows an increasing trend .Soil and water conservation must be enhanced to reduce the non-point source pollution caused by soil and water losses above the Guojiatun Station.The point source pollution in the lower reaches of the Luanhe River should be controlled .
