根据实地调查和水文资料，将阜阳河划分为5个河段，分析了总氮、总磷、COD、氨氮和硝酸盐等主要污染物的空间相似性和差异性。采用主成分分析法（PCA）对污染物进行了源解析。结果表明，阜阳河大部分水样的主要污染物均低于V类标准，可分为3类：第一类主要分布在邯郸段，主要由天然沃茨补给。第二类和第三类分别位于上游和下游，非常规沃茨补给的主要污染物的浓度变化很大，尤其是氨氮。此外，主要污染物有三种来源，耗氧有机污染物，氮、磷污染物在不同河段的贡献率不同。
The Fuyang River has suffered from severe pollution and many non-flow events.Based on the field investigation and the hydrological data,the river is divided into five reaches.The spatial similarities and differences of the main contaminations,including total nitrogen,total phosphorus,COD,ammonia and nitrate,are analyzed.Source apportionment of the contaminations are conducted by the Principal Component Analysis(PCA).The results show that the main contaminations of most water samples in the Fuyang River are inferior to V standard.The water samples can be divided into 3 categories.The first category is mainly distributed in the Handan section,recharged mainly by the natural waters.The second and the third categories are in the upstream and the downstream sections,separately,that are recharged by unconventional waters.The concentration of the main contaminations vary greatly especially for ammonia.In addition,there are three kinds of sources of the main contaminations,oxygen consumption organic pollutants,nitrogenous pollutants and phosphorous pollutants which have different contributions in the different reaches.
