摘　　要：基于阿什河2008—2010年水质监测和流量监测结果,利用改进的埃特金和相关性拟合插值法,补全监测条件限制造成的缺失数据,再利用基流分割法,估算阿什河面源氮和磷污染输出量,分析其污染特征。结果显示:阿什河进入松花江的污染负荷峰值一般出现在3—5月或者7—9月,主要由春汛或夏汛造成,峰值出现时污染来源以面源污染为主。2008—2010年阿什河面源污染输出量表现出TP减少,TN和NH_4^+-N增加的趋势。阿什河年均输出量TN约为5 436.6 t,NH_4^+-N约为3 057.8 t,TP约为554.8 t,其中,点源污染为2 775.8、1 440.7、250.8 t,面源污染为2 660.7、1 630.7、304.1 t,面源污染占总量的50%左右。The improved Aitkin and correlation fitting interpolation method were used to complemented missing data by limited monitoring conditions,the base flow segmentation method were then used to estimated non-point source of nitrogen and phosphorus pollution output load of the Ashi River into the Songhua River,its pollution characteristics were analyzed,based on monitoring data of water quality and flow in the Ashi River from 2008 to 2010.The results showed that total nitrogen（TN） about5 436.6 t,ammonia（NH4＋-N） about 3 057.8 t,total phosphorus（TP） about 554.8 t of the Ashi River were discharged into the Songhua River per year,which point source pollution were 2 775.8,1440.7 and 250.8 t,non-point source pollution were2 660.7,1 630.7,304.1 t respectively,non-point source pollution accounts for about 50% of the total output.Ashi River pollution output amount emerged TP reduce,TN and NH4＋-N added feature from 2008 to 2010.The TP,TN and NH4＋-N amount of the Ashi River into the Songhua River were comprehensively analyzed each month from 2008 to 2010,the pollution output peaked in March-May or July-September,mainly caused by the spring flood or summer flood,when the peak pollution source was non-point source pollution generally.
