摘　　要：在现有技术条件下,运用相对简单可行的方法对太湖流域的非点源污染负荷进行了初步估算。通过实地监测和调查,获得了土地利用、生活污染、畜禽养殖以及水产养殖等不同类型污染源的产污系数,并与遥感、G IS技术相结合,分别计算了太湖流域农田、生活、畜禽养殖、水产养殖等不同类型污染源的污染负荷。计算结果表明,畜禽养殖和生活污染是太湖流域非点源污染的主要来源,畜禽养殖的TN、TP和COD污染负荷分别占流域总污染负荷的34%、58%和61%,农田污染所占比例并不突出。应将畜禽养殖和生活污染作为太湖流域非点源污染控制的重点。Under the current technological conditions,a relatively simple method was used to estimate non-point source pollution（NPS） load in the Taihu Lake Basin.Through field survey and investigation,pollutant producing coefficients of various types of pollution sources,i.e.,farming,rural and urban domestic wastes,livestock and poultry breeding,and aquiculture were obtained.The coefficients were used in combination with remote sensing and GIS data to calculate pollution loads of various types of pollution sources,separately.Results show that domestic activity and livestock and poultry breeding are the main sources of NPS in the region,contributing 34%,58% and 61% to the total pollution load of the region in TN,TP and COD,respectively,while farmland has a relatively small share in NPS.Therefore,it is essential to set livestock and poultry breeding and domestic activity as priority for control of NPS in the Taihu Lake Basin.
