摘　　要：沿通惠河干流自上而下选取11个水样监测点,在1年内每月1次测定其CODCr、NO3--N、NH4+-N和TP等水质参数并采用单因子评价法对其水质状况进行评价。结果表明,通惠河干流水质在丰水期稍好于平水期和枯水期,所有时期的上段河段水质均略好于下段河段,但在整个监测期内均为劣于Ⅴ类水质,未能达到其水功能区划的水质类别要求,对通惠河干流水环境综合治理起到了积极的参考作用。Four water quality indicators （ including CODcr, NO3-N, NH＋-N and rip ） are monitored once every month within one year for the eleven monitoring sections along the Tonghui River and the water quality for the Tonghui River is evaluated by the single -factor evaluation method. The results show that the water quality in the wet season is better than that in the normal and dry season and it is better in the upper river （ Dongbianmen Bridge to Gaobeidian Brake） than that in the lower river （ Gaobeidian Brake to the Tongji Bridge）. However, the water quality in the whole monitoring period is always worse than the Grade V, which is not able to meet the water function zoning requirements for the Tonghui River. The findings serves as a basic reference for the water environ- ment improvement in the Tonghui River.
