基于江苏省2007年、2009—2011年4次污染源普查资料，选取COD和NH3－N为研究因子，统计江苏省太湖流域2007年、2009—2011年污染物排放变化规律；根据已核定的区域纳污能力以及总量控制值，对研究区域入河量及排放量进行削减分析（以2010年为现状年）。结果表明：①2007年、2009—2011年江苏省太湖流域污染物排放总量逐年下降，其中城镇点源所占比例呈逐年下降趋势，面源比例呈增长趋势；②“十二五”期间，江苏省太湖流域COD和NH3－N的入河量削减率分别为20％和65％；③“十二五”期间，江苏省太湖流域COD和NH3－N的点源排放削减率分别为27％和35％。

Based on four large-scale censuses of pollution sources in 2007, 2009, 2011 in Jiangsu Province, selecting pollutant discharge rule of chemical oxygen demand ( COD ) and ammonia nitrogen ( NH3-N ) as the research object, the pollutant discharge tendency in Taihu Lake Basin in 2007,2009-2011 is fixed out.According to the defined allowable permitted assimilative capacity and the controlled discharge volume for point pollution source, the cut rate for the total volume was derived.Results indicate as follows:(1) the total discharge volume of pollution declined in Taihu Lake Basin of Jiangsu Province in 2007,2009-2011.The proportion of urban point-source declined while the proportion of non-point source had the tendency of rise;(2) The export load of COD and NH3-N in Taihu Lake Basin of Jiangsu Province should be decreased by 20%and 65%in the research area during the twelfth-five-year period;(3)the cut rate of point source discharge volume of COD and NH3-N should be 27%and 35%in the research area in the twelfth-five-year period.
