摘　　要：使用问卷调查法对舒城县丰乐河小流域农业面源污染现状进行实地调研,采用等标污染负荷法对流域区域内千人桥镇和桃溪镇的农业种植污染、畜禽养殖污染与农村生活污染进行综合分析。研究表明,在舒城县丰乐河小流域两个乡镇的农业面源污染排放源中,种植业TN、TP的排放量为45.78 t,污染负荷率为20.75%;畜禽养殖业COD、TN、TP的排放量为26.59 t,污染负荷率为12.05%;农村生活源COD、TN、TP的排放量为148.28 t,污染负荷率为67.20%。在选择的3个评价因子中,COD的污染负荷率最高(69.47%),其次为TN(28.22%),TP最低(2.31%)。农村生活污染是该小流域农业面源污染物的主要来源,也是农业面源污染控制的重点。The present situation of agricultural non-point source pollution in Fengle River watershed in Shucheng County was investigated by questionnaire survey method.The pollution from planting,livestock and poultry breeding and rural life in Qianrenqiao Town and Taoxi Town in the watershed were comprehensively analyzed by the equivalent pollution load method.The study showed that in the agricultural non-point source pollution in the two towns,TN and TP emission from planting was 45.78 t,the pollution load rate was 20.75%.COD,TN and TP emission from livestock and poultry farming was 26.59 t,the pollution load rate was 12.05%.The emission of COD,TN and TP from rural life was 148.28 t,the pollution load rate was 67.20%.Among the three selected evaluation factors,the pollution load rate of COD was the highest(69.47%),the next was TN(28.22%),TP was the lowest(2.31%).Rural domestic pollution was the main source of agricultural non-point source pollutant in the watershed,and was also the key point of agricultural non-point source pollution control.
