摘　　要：于2008年1月,在杭州西湖及京杭大运河杭州城区段各设6个采样站,依据《水和废水监测分析方法》对杭州西湖及京杭大运河杭州城区段水体的水温(T)、pH值、溶解氧(DO)、五日生化需氧量(BOD5)、化学需氧量(CODCr)、总氮(TN)和总磷(TP)等理化指标进行测定.参照《水质标准汇编》(下册)有关"地表水环境质量标准基本项目标准限值"对两水域的水质进行大体评价,对比两水域的水质状况.结果表明:1)京杭大运河杭州段上游入口处(样站1)水质好于运河杭州城区段;2)杭州西湖水域呈现的理化指标(平均值DO:9.96mg/L,CODCr:19.00mg/L,BOD5:1.25mg/L,TN:2.88mg/L,TP:0.247mg/L)均好于京杭大运河杭州城区段水域(平均值DO:5.54mg/L,CODCr:25.95mg/L,BOD5:3.05mg/L,TN:6.21mg/L,TP:0.525mg/L);3)两水域的TN和TP(TN:西湖为2.13～3.88mg/L,运河为4.83～9.15mg/L;TP:西湖为0.099～0.376mg/L,运河为0.429～0.752mg/L)含量明显超标,均属典型富营养化水体.In January 2008,six sampling stations were set up respectively in the West Lake（Hangzhou） and Hangzhou urban section of Beijing-Hangzhou Grand Canal.According to ＂water and wastewater monitoring and analysis methods＂,the experiment measured physical and chemical indexes of them,including the water temperature（T）,pH value（pH）,dissolved oxygen（DO）,biochemical oxygen demand（BOD5）,chemical oxygen demand（CODCr）,total nitrogen（TN） and total phosphorus（TP）.Referring to the ＂limiting value about the basic items of environmental quality standard for surface water＂ from ＂compilation of water quality standard＂,and comparing the water quality of two water areas,the results show that the water quality of the upstream section in Hangzhou section of Beijing-Hangzhou Grand Canal（sampling station 1） is better than that of the urban section.Overall,the water quality of West Lake（Hangzhou）（average DO is 9.96 mg/L,CODCr is 19.00 mg/L,BOD5 is 1.25 mg/L,TN is 2.88 mg/L,TP is 0.247 mg/L） is better than that of Hangzhou urban section of Beijing-Hangzhou Grand Canal（average DO is 5.54 mg/L,CODCr is 25.95 mg/L,BOD5 is 3.05 mg/L,TN is 6.21 mg/L,TP is 0.525 mg/L）.Two water areas TN（the TN of West Lake（Hangzhou） is 2.13-3.88 mg/L,and the TN of Hangzhou urban section of Beijing-Hangzhou Grand Canal is 4.83-9.15 mg/L） and TP（the TP of West Lake（Hangzhou） is 0.099-0.376 mg/L,and the TP of Hangzhou urban section of Beijing-Hangzhou Grand Canal is 0.429-0.752 mg/L） significantly have levels exceeding the standard,it means that they belong to typical eutrophic water.
