摘　　要：随着养羊规模的不断发展,羊粪囤积量不断增加,对环境及人类的生产生活有很大影响。因此,合理处理羊粪对整个生态环境具有重要的意义。堆肥处理是畜禽粪便无害化、资源化利用的一种重要方式。该文对不同阶段自然放牧的凉山黑绵羊粪便特性进行了分析并比较了堆肥前后粪便主要污染物的变化。结果表明羔羊粪便中的自然含水率远低于哺乳母羊与空怀母羊,但粪便中有机质、全氮、全磷、砷、铅、镉、铜、锌和镍的含量均高于哺乳母羊与空怀母羊,而哺乳母羊与空怀母羊粪便中上述指标的含量差异不大。经过堆肥发酵后羊粪中的有机质的含量下降,全氮和全磷的含量增加,重金属铅的含量下降,铜和锌的含量增加。The continuous development of sheep breeding scale has led to the increase of sheep manure and impacted the environment and people's life.Therefore,reasonable disposal of sheep manure is of great significance to the whole ecological environment.Composting is an important way of resource utilization of livestock manure,which is harmless.In this paper,the characteristics of grazing sheep manure at different stages are analyzed and the changes of the main nutrients in the manure before and after composting are compared.The results show that the natural water content in the feces of lamb was far lower than that of sheep at non-pregnant and lactation period,but the contents of organic matter,total nitrogen,total phosphorus,arsenic,lead,cadmium,copper,zinc and nickel in the feces of lamb were all higher than those of sheep at non-pregnant and lactation period,and the contents of these indexes in the feces of sheep at non-pregnant period and lactation period were not significantly different.After composting,the content of organic matter in sheep manure decreased,the content of total nitrogen and total phosphorus increased,the content of lead decreased,and the content of copper and zinc increased.
