摘　　要：为改善小清河水质污染状况,保护莱州湾水环境,根据2008~2017年小清河下游监测断面数据,分析小清河下游水环境质量状况,估算污染物入海通量并讨论污染物入海通量主要影响因素。结果表明:10年间小清河下游水环境质量呈好转趋势,超出《地表水环境质量标准》(GB3838-2002)Ⅲ类水质标准的污染物主要是石油类、COD和TP,石油类为小清河下游的首要污染物。小清河年均污染物入海总量约为181 732t,其中COD入海通量起主导作用。各类污染物入海通量主要受径流量、污染物浓度和时间因素影响,且各类污染物入海通量及入海总量年际变化均呈下降趋势。In order to improve the water pollution situation in the Xiaoqinghe River and protect the water environment of Laizhou Bay,according to the monitoring section data of the downstream in the Xiaoqinghe River during 2008-2017,this paper analyzed the water environment quality,estimated the pollutant fluxes into the sea and discussed its main influencing factors.The results show that the water quality in the lower reaches of Xiaoqinghe River has been improving in the past 10 years.The pollutants that exceed the Class III water quality standard of Surface Water Environmental Quality Standard(GB3838-2002)are mainly petroleum,COD and TP,and petroleum is the primary pollutant one.The annual average amount of pollutants into the sea is about 181732t,among which COD is the dominant one.The fluxes of various pollutants into the sea are mainly affected by runoff,pollutants concentration and time factor.The annual fluxes and total amount of various pollutants into the sea show a decreasing trend.
