摘 要:基于汾河临汾段石滩、甘亭、临汾、柴庄四个监测断面2008~2013年的常规水质监测数据,采用有机污染综合指数法研究该段水体有机污染状况,并对影响水质的主要因素进行分析.结果表明:化肥施用量的大幅下降与政府治污措施的实施,使得汾河临汾段水体有机污染状况呈下降态势,但由于人口密度增加,用水量及污水排放量提高,生产规模扩大等不利因素影响,主要有机污染物含量仍超出水环境质量IV类标准,污染形势依然严峻.依据汾河临汾段水污染现状及原因提出科学的治理对策.Based on the conventional water quality data from the four monitoring sections of Shitan,Gan Ting,Lin fen and Chaizhuang in Linfen section of Fenhe River from 2008 to 2013,the organic pollution of water body was studied by the organic pollution comprehensive index method,and also the principal factors affecting water quality were analyzed.The water pollution of the Linfen section was improving,thanks to the reduced amount of fertilizer use and the implementation of government's anti-pollution measures;but pollution situation is still grim,for the content of major organic pollutants still exceed Class IV standard concerning water environment quality,due to the increasing population density,amount of water consumption and sewage discharge,the enlarged scale of production and other unfavorable factors.Then based on the main factors affecting the water quality of Fen River in Linfen area,the corresponding measures for scientific administration were put forward.
