摘　　要：目的掌握鸭绿江中上游水域水质变化规律及理化常规指标自然本底值。方法按环境保护总局HJ/T 52-1999《水质河流采样技术指导》,在表层水下30 cm深度、距江边2 m处逆向水流采集水样,按《生活饮用水标准检验方法》进行检测。结果鸭绿江中上游水中主要离子有铁、锰、砷、铝、镁、硫酸盐、氯化物、氟化物、硝酸盐,自然本底值分别为0.28、0.031、0.002、0.03、4.28、12.3、3.76、0.13、0.89 mg/L。结论鸭绿江中上游水域基本符合《生活饮用水卫生标准》水源水质限值要求及《地表水环境质量标准》GB 3838-2002 Ⅱ类水质限值要求,经净化消毒处理后,可以作为人类生活饮用水水源及珍稀水生生物栖息地。Objective To explore changes of water quality in the middle and upper reaches of Yalu River,determine background values of routine physical and chemical indicators.Methods Water samples were collected according to HJ/T 52-1999 River Water Quality Sampling Guidance,water samples were detected according to GB/T 5750-2006 Drinking Water Standard Test Method.Results Background values of major indicators existed in water were iron 0.28 mg/L,manganese 0.031 mg/L,arsenic 0.002 mg/L,aluminum 0.03 mg/L,magnesium 4.28 mg/L,sulfate 12.3 mg/L,chloride 3.76 mg/L,fluoride 0.13 mg/L,nitrate（in terms of nitrogen） 0.89 mg/L.Conclusion Water quality of middle and upper reaches of Yalu River basically accord with the requirements of national standards（GB 5749-2006 and GB 3838-2002）,it can be used as human drinking water source after purification and disinfection.
