摘要:
利用2015 年里下河33 个监测断面的6 个水质指标数据，综合运用单因子水质评价法、综合水质评价法、箱线图法和因子分析法分析了扬州里下河地区水体污染物的时空分布特征及污染源解析。结果表明：综合水质评价较好的水质占58.4%，较差的水质占34.6%，极差的水质占7.0%，汛期水质差于非汛期；主要污染物的空间差异较大，氨氮的差异最为明显；河流水环境污染物主要有2 种，分别是耗氧型有机污染物和氮类、磷类污染物，对整个里下河污染的贡献率分别为57.13% 和16.70%。耗氧型有机污染物主要来源为生活污水和工业废水，氮磷类污染物主要来源为农业面源和水产养殖。
Abstract:
Using 6 water quality indicators in 33 monitoring sections of Lixiahe during 2015，the temporal and spatial distribution characteristics and pollution sources of Yangzhou Lixiahe region are analyzed in this paper via a comprehensive use of single factor water quality evaluation method; integrated water quality evaluation method; box plot method and factor analysis method.The results show that 58.4% of water quality is moderately good，34.6% of water quality is poor，and 7.0% of water quality is very poor.Besides，flood season water quality is worse than non-flood season.The main pollutants greatly vary spatially，with the ammonia nitrogen difference being most obvious.There are two kinds of river water pollutants namely oxygen-based organic pollutants and nitrogen，phosphorus pollutants.Their contributions to entire Lixiahe region pollution are 57.13% and 16.70%，respectively.The main sources of oxygen-based organic pollutants are domestic sewage and industrial wastewater while the main sources of nitrogen and phosphorus pollutants are agricultural non-point source and aquaculture.
