采用源解析法对工业污染源、生活污染源、农业面源（含种植业、养殖业）进行分析，并统计分析了武宜运河全线水质现状。结果表明，农业面源是武宜运河流域总氮、总磷污染的主要来源，且以养殖业为主，生活污染源是太湖流域氨氮污染的主要来源，且以农村生活污水为主；武宜运河水质以氮磷污染为主，总氮污染最为严重。武宜运河核心区研究范围占总研究范围的比例为35%，总氮、氨氮和总磷入河量分别占研究范围内各类污染物总入河量的42.8%，45.0%，34.1%，污染分布重点区域为武进前黄镇、牛塘镇及宜兴和桥镇所辖行政村。研究范围内农业面源污染分布重点区域为武进前黄镇、牛塘镇、宜兴屺亭街道及和桥镇；生活污染源氮磷污染物排放主要来自高新区及牛塘镇的农村生活污水排放，其次是屺亭街道和前黄镇的农村生活污水。
採用源解析法對工業汙染源、生活汙染源、農業麵源（含種植業、養殖業）進行分析，併統計分析瞭武宜運河全線水質現狀。結果錶明，農業麵源是武宜運河流域總氮、總燐汙染的主要來源，且以養殖業為主，生活汙染源是太湖流域氨氮汙染的主要來源，且以農村生活汙水為主；武宜運河水質以氮燐汙染為主，總氮汙染最為嚴重。武宜運河覈心區研究範圍佔總研究範圍的比例為35%，總氮、氨氮和總燐入河量分彆佔研究範圍內各類汙染物總入河量的42.8%，45.0%，34.1%，汙染分佈重點區域為武進前黃鎮、牛塘鎮及宜興和橋鎮所轄行政村。研究範圍內農業麵源汙染分佈重點區域為武進前黃鎮、牛塘鎮、宜興屺亭街道及和橋鎮；生活汙染源氮燐汙染物排放主要來自高新區及牛塘鎮的農村生活汙水排放，其次是屺亭街道和前黃鎮的農村生活汙水。

T he sources of industrial pollution, the sources of domes tic pollution, and the non-point source of agricultu ral pollution (including planting and aquaculture) are analyzed by source apportionment;the water quality of Wuyi canal is also analyzed by statistics. The result shows that non-point source agricultural pollution is the main source of the total nitrogen and total phosphorus in the Wuyi canal, and the planting contributes the most;domestic pollution is also an important source of the total nitrogen and total phosphorus in the Wuyi canal, and rural domestic sewage contributes the most. The nitrogen and phosphorus pollution dominates the Wuyi canal, especially the total nitrogen pollution is the most serious. The core area of Wuyi canal occupies 35% of the total research scope. The quantity of nitrogen, ammonia nitrogen andphosphorus pollution which flow into the canal respectively occupies 42.8%, 45.0%, 34.1% of all the pollutant flowing into the canal. The most serious contaminated areas are Qianhuang town, Niutang town in Wujin district and Heqiao town in Yixing. The main areas that the non-point source agricultural pollution distributed in are Qianhuang town, Niutang town in Wujin district, and Qiting community, Heqiao town in Yixing. The nitrogen and phosphorus pollution contained in the rural domestic sewage are mainly from Gaoxin district and Niutang town, secondly from Qiting community and Qianhuang town.
