摘　　要：村落非点源污染是白洋淀流域农业非点源污染的重要组成部分.现场调查府河干流临河村落生活污水、生活垃圾的排放情况及相应污染物含量,研究了其非点源污染特征.结果表明:临河村落生活污水与生活垃圾的人均排放量分别为26.3 L/d和0.41 kg/d;临河村落非点源氮、磷污染中,生活垃圾贡献极大,在TN、TP年潜在入河负荷和年入河负荷中所占比例均接近70%;生活污水中的氮、磷以可溶态为主;生活污水与人粪尿的CODCr年入河负荷分别为10.9和2.30 t,生活垃圾的TOC年入河负荷为26.9 t.The characteristics of non-point source pollution（NPS） in villages along the Fuhe River in the Baiyangdian watershed were studied based on field investigations of the discharge of village sewage and household wastes,and the contents of pollutants in these sewages and wastes.The results showed that the daily discharge of sewage and household wastes from the villages was 26.3 L and 0.41 kg per capita,respectively.The household wastes contributed greatly to the N and P pollution loads of the Fuhe River,with the relevant entering loads as high as about 70%.N and P in the sewage were mainly the soluble ones.The amount of CODCr in the sewage and human excrements was 10.9 and 2.30 t/a,respectively,while the amount of TOC in the household wastes was 26.9 t/a.
