摘　　要：对广州市S区地表水水质特征及其影响因素进行分析,为S区地表水整治提供理论基础。采用2009至2018年的水质监测数据,对水体中的总磷和氨氮的时空分布进行分析,采用单因子评价法和内梅罗指数法对水质进行评价,并对影响水质变化的因素进行探讨。总体来看,氨氮与总磷的PIp均小于1。在时间上,2012年起各断面水质均开始好转;在空间上,C断面因为受工业区废水的影响,特征污染物浓度较其他断面高;污染物的浓度呈由北向南递减的趋势;B断面在2018年水质变差。“十三五”期间,S区水环境质量整体呈好转趋势,但形势依然严峻,应进一步多举措并行严控总磷排放。Characteristics of water quality variation and its impact factors were analyzed in S district to provide theoretical basis for the eutrophication mechanism of Guangzhou city.Monitoring data from 2009to 2018were used to analyze the spatio-temporal distribution of Ammonia and phosphorus.Single factor assessment method and Nemero index method were used to evaluate the water quality and the main impact factors were discussed.The PIpof the Ammonia and phosphorus were all less than 1.The results showed that since 2012,surface water environments quality has been improved.The particular pollutants of C water section was higher than other sections because of the industrial sewage.The concentration of pollutants decreased from north to south.B water section had poor water quality in 2018.During the period of“13th Five-year”,surface water environment quality in S district has been improved,but the situation is still severe.It is important to take more measures to control phosphorus emissions.
