摘　　要：通过污染物流失系数法研究了赵王河流域2009年种植业化肥污染负荷。结果表明,2009年赵王河流域种植业化肥TN的流失量为427.55 t,TP的流失量为57.13 t,CODCr流失量为933.76 t,氨氮流失量为186.75 t;CODCr、氨氮、TN、TP的入河量分别为93.38、18.68、42.76、5.71 t,其中,CODCr入河量最大,其次是TN,再次是氨氮,TP最少。With the method of pollutants loss coefficients, pollutants loads of fertilizers of crop farming in Zhaowang river basin in 2009 were studied. The results showed that in 2009, the amount of TN loss from fertilizers of crop farming in Zhaowang river basin was 427.55 t; and the amount of TP loss was 57.13 t, CODcr 933.76 t and NH3-N 186.75 t; pollutants loads delivered into rivers amounted to CODcr 93.38 t, NH3-N 18.68 t, TN 42.76 t and TP 5.71 t. Of the four pollutants, CODcr contributed to the maximum of pollutants loads delivered into rivers, TN the second, NHe-N the third and the last one was TP.
