摘　　要：选取太湖流域典型农村9户农户(高、中、低收入水平各3户农户)作为研究对象,采用现场监测及入户调查的方法对农户生活垃圾污染物产排系数进行为期一年的系统定量研究,结果表明:收入水平对农户总垃圾、有机垃圾、有机垃圾TN、TP产排污系数及可回收垃圾产污系数影响极显著(P<0.01),具体表现为高收入农户>中收入农户>低收入农户,但对农户有害垃圾产排污系数及可回收垃圾排污系数无显著性影响(P>0.05)。因此,除有害垃圾产排污系数及可回收垃圾排污系数外,农户总垃圾、有机垃圾、有机垃圾TN、TP产排污系数及可回收垃圾产污系数可按收入水平划分。各收入水平农户有机垃圾占总垃圾比例超过80%,表明有机垃圾的综合利用效率特别是畜禽养殖率是影响生活垃圾污染物排放系数的主导因素,而农业收入水平则对这种因素影响显著。Nine households of high,medium and low income leve（l3 households with 3 income level）were selected as representative household of Tai Lake basin and the following issue were studied to the measuring method of producing and discharge coefficient of rural household waste：producing coefficient of rural household waste monitoring,comprehensive utilization situation of rural household waste investigation,discharge coefficient of rural household waste calculation.The results showed that effect of income level on producing and discharge coefficient of total waste,organic waste,TN and TP in organic waste and producing coefficient of recyclable waste was significant,which followed as high income level household medium income level household low income level household.But no significant influence was observed on producing and discharge coefficient of harmful waste and discharge coefficient of recyclable waste.Therefore producing and discharge coefficient of total waste,organic waste,TN and TP in organic waste and producing coefficient of recyclable waste can be divided according to income level.More than 80% household waste were organic waste,so the utilization efficiency o（fdomestic animals）organic waste was dominant factor to influence producing and discharge coefficient of rural household waste contaminant,and agricultural income level had significant influence on this factor.Higher agricultural income level lead to higher organic waste comprehensive utilization efficiency and lower the pollutant emission.The ratio of discharge amount to producing amount of TN and TP in organic waste with high,medium and low income level household were 29.41%,23.15% and 9.76% respectively.
