摘　　要：为了解银川市畜禽养殖污染情况,根据统计资料和文献数据,在确定计算参数和计算方法后,分析计算银川市畜禽粪尿中铜、锌、总氮、总磷、化学需氧量及氨氮的产生量,同时对氮、磷耕地负荷能力进行分析,从而评估银川市畜禽粪尿污染潜力风险.结果表明,2013年银川市畜禽粪尿中总氮、总磷、铜、锌、化学需氧量和氨氮的产生量分别为15 600,1 690,20,43.2,282 000和1 810t,各畜禽粪尿总量为2.51×106 t.银川市畜禽粪便负荷量承受程度的警报值R=0.53,畜禽粪尿的耕地承载量为15.77t/hm2,单位耕地粪尿中氮的承载量为94.28kg/hm2,单位耕地粪尿中磷的承载量为10.21kg/hm2.In order to understand the livestock pollution situation in Yinchuan,the article analyzes and calculates according to the statistical material and computing method the generated quantity of livestock and poultry manure and its copper,zinc,total nitrogen,total phosphorus,chemical oxygen demand and ammonia nitrogen after ascertaining the calculating parameter and computing method of Yinchuan livestock and poultry manure.Meanwhile,it analyzes the cultivated land load ability of nitrogen and phosphorus in the manure of livestock and poultry to assess the hazard of manure＇s pollution possibility in Yinchuan.The result shows that the chemical oxygen demand and generated quantity of ammonia nitrogen of total nitrogen,total phosphorus,copper,zinc are 15600,1690,20,43.2,282000,1810 trespectively,the total amount of all livestock and poultry is,however,2.51×106 t.The alarm value of Yinchuan livestock and poultry manure load degree Ris 0.53,while the farm land load-carrying capacity of livestock and poultry manure is 15.77t/hm2,the unit farm land manure biological bearing capacity is 94.28kg/hm2,and the unit farm land bearing capacity of manure phosphorous is 10.21kg/hm2.
