摘　　要：研究对淮河干、支流1985-2008年的水质变化趋势进行了分析。结果表明,淮河干流水体的主要污染物为NH3-N,其浓度波动范围为0~10.0 mg/L,超标的现象频繁出现,年均值为1.35 mg/L。支流淠河和干流均达到地表Ⅲ类水质标准,淮北支流沙颖河水质最差,劣于地表Ⅴ类水质标准。干流水质在1991-1999年期间显著恶化,但2000年以后水质逐渐改善,淮河流域污染物入河总量的大幅度削减是淮河水质改善的重要原因。The water quality variation of Huaihe River in the recent twenty years was studied on the data covering 1985-2008. NH3-N was the main pollutant, which exceeded the standard phenomenon occurs frequently,varying from 0 to 10.0 mg/L,with the average of 1.35 mg/L. The water quality in the mainstream and the Pi River meet the surface water quality standardⅢ, while the water quality in Shaying river can't meet the surface water quality standard Ⅴ. The water quality in the mainstream deteriorate during 1991-1999,but improved since the year of 2000,owing to the substantial reduction of pollutant from Huaihe river basin.
