摘要
基于已有研究结果和实际调查资料,采用排污系数法,对乌梁素海流域COD、TN、TP污染负荷进行估算。结果表明,2008年乌梁素海流域COD、TN、TP污染负荷总量分别达39.3、6.95、0.91万t/a,其中畜牧养殖业和农田面源是主要的贡献源,其污染负荷分别占COD负荷总量的23.5%和31.1%、TN负荷总量的40.3%和25.2%、TP负荷总量的61.1%和13.5%。乌梁素海富营养化控制的关键是降低农牧业污染排放,而处于转型期流域的工业污染也不容忽视,并针对这3类污染源提出防治对策。
Based on past research and actual survey data, the pollution load of chemical oxygen demand （ COD）, total nitrogen＇ （TN） and total phosphorus （TP） in Wullangsuhai basin were evaluated by the ＇methOd of pollution discharge coefficiem. The results indicated that total discharge of COD, TN, and TP were 39.3,6.95, and 0.91 ten thousand t/a, respectively. Livestock waste and agricultural non-point source pollution were the primary discharge source of COD （23.5% and 31. !% ） ,TN （40.3% and 25.2% ） and TP （61： 1% and 13.5% ）. Thus,it was suggested that the reduction of livestock waste and agriculiural pollution was critical for Wutiangsuhai eutrophication control;meanwhile, the discharge of indus- trial point source was also innegligible. Several feasible suggestions were proposed for the control of above three pollution sources.
