摘　　要： 以三峡库区重庆段的3个典型行政农村中不同经济收入水平、不同生活方式条件下的18家农户为研究对象,分别对其每月连续3天产生的生活垃圾产生量及特征污染物种类、浓度等参数进行了12个月的跟踪监测。监测表明三峡库区附近农村3个区的生活垃圾人均日产量分别为0.206、0.383和0.426 kg/(人.d)。垃圾平均容重为0.34 kg/L,且垃圾组成以有机成分(植物、剩饭菜等)为主,约占60.22%。借助SPSS(社会统计学软件)对三峡库区农村生活垃圾的产量以及垃圾成分与经济条件和生活方式之间的关系做了详细分析,找出了含水率与有机垃圾的百分含量之间的相关性。有机垃圾含氮含磷量分别为2.39%和0.31%,并进一步比较了农村生活垃圾和生活污水中氮磷的排污系数。 18 rural households from the 3 classical districts of Three Gorges Reservoir Area under different economic and life conditions of rural districts were selected as research object, the study carried out tracking monitoring for 12 months on domestic waste production and types, concentrations and other parameters of characteristic pollution which are produced in continuous 3 days of each month. The result showed that the output of daily domestic waste of Three Gorges Reservoir Area in the three rural districts were 0.206, 0.383 and 0.426 kg/（ cap· d） , respectively. Average volume weight of waste was 0.34 kg/L, and the major components of waste （ plant, residual rice and vegetable and others） were organic wastes, about 60.22%. The relationship between output of domestic waste and the economic and life conditions was ana- lyzed by using SPSS software, the correlation between the water content and the percentage of organic waste were also analyzed in detail. The content of N and P in organic waste were 2.39% and 0.31%, it also compared with the emission coefficient of N and P in the rural domestic waste and sewage.
