摘　　要：为推动区域畜禽粪污资源化利用,实现农业可持续发展,利用黑龙江省富裕县畜禽生产、农作物种植资料和数据,分析县区内畜禽粪污土地负荷和畜禽粪污土地承载力。结果表明:2019年富裕县农作物总氮需求量为17493.1 t,畜禽粪肥总的氮养分生产量为8425.2 t;单位面积粪肥养分供给量为38.23 kg·hm^-2,单位面积耕地粪肥养分需求量为45.36 kg·hm^-2,需求量大于供给量,说明富裕县畜禽粪便的污染程度较低且有广阔的消纳空间。In order to promote the resource utilization of livestock and poultry manure and realize the sustainable development of agriculture,the data of livestock and poultry production and crop planting in Fuyu County of Heilongjiang Province were used to analyze the land load and bearing capacity of livestock and poultry manure in Fuyu County.The results showed that,in 2019,the total nitrogen demand of crops in Fuyu County was 17493.1 t,the total nitrogen nutrient production of livestock manure was 8425.2 t;the nutrient supply of manure per unit area was 38.23 kg·hm^-2,and the nutrient demand of manure per unit area of cultivated land was 45.36 kg·hm^-2,which indicated that the pollution degree of livestock and poultry manure in Fuyu County was relatively low and there was a wide space for accommodation.
