摘　　要：通过测定大理地区毛驴的粪便成分,并与人、猪、牛、马和羊粪便成分进行对比,参照我国相关标准得出:毛驴尿液总氮浓度是富营养化指标的2.65倍,毛驴尿液的化学需氧量和生化耗氧量分别是集约化畜禽养殖业水污染最高允许日均排放浓度的9.4倍和7.8倍;毛驴粪中有机质含量与马粪接近,仅次于羊粪;相比其它五种粪,毛驴粪总氮含量最低,总磷含量居中,铁和锌依次是绿色食品肥料使用准则最大允许含量的19.4倍和1.4倍。这将为大理市内饲养毛驴与洱海周边环境生态的统筹提供科学依据。By measuring the composition of Dali donkey droppings and comparing with human,pig,ox,horse and goat manure composition,draw a conclusion with reference to relevant China standards： Nitrogen concentration in donkey urine was 2.65 times of the eutrophication indicator,Chemical oxygen demand and biochemical oxygen demand in donkey urine was 9.4 times and 7.8 times respectively of the maximum allowable daily discharge of water pollution concentration in the intensive livestock industry.Donkey dung and horse manure,organic matter content in close second only to the sheep manure,compared to other five kinds of dung,donkey manure nitrogen content of the lowest,the highest content of total phosphorus,donkey manure in the iron and zinc followed the guidelines for the maximum allowable green manure content of 19.4 times and 1.4 times.
