摘　　要：根据2007～2011年水质监测资料，对滦河干流CODMn和NH3-N浓度的时空变化进行分析。结果表明，2010年枯水期污染物浓度较低，而平水期浓度则较高；2007～2011年污染物浓度呈现逐渐降低趋势，即水质有所改善。以2010和2011年为例，对滦河干流进行简单的水质水量联合评价，郭家屯和鸟龙矶站点水量较大时水质较差，水量较小时水质较好，呈现面源污染的特点；滦县站点水量较大时水质较好，水量较小时水质相对较差，呈现点源污染的特点。According to water quality monitoring data during 2007 - 2011, the temporal-spatial variation of CODMn and NHz-N in mainstream of Luanhe River was analyzed. The results showed that： the pollutant concentration was low in the dry season, while it was comparatively high in the normal water season in 2010. The pollutant concentration decreased and the water quality improved during 2007 -2011. The correlation was analyzed in terms of integrating water quality and quantity, based on the data collected over the period from 2010 to 2011. The water quality of Guojiatun and Wulongji sample was good with a small amount of water and was poor with large quantity of water, which presents the characteristics of non-point source pollution. The water quality of Luanxian sample was good with large quantity and was poor with a small amount of water, which presents the characteristics of point source pollution.
