摘　　要：为进一步了解菏泽市畜禽粪便产生量对有效耕地污染现状,根据《2023菏泽统计年鉴》中畜禽养殖数据,利用排污系数估算了2022年菏泽市各县区畜禽粪便产生量、耕地负荷等指标。结果表明,2022年菏泽市畜禽粪便总排放量约为1557.73万t,按年粪便产生量排序,依次为猪>家禽>羊>牛。2022年菏泽市平均耕地负荷量为25.21 t·hm^(-2),警报值级别处于Ⅲ,其中耕地负荷居全市第一的是郓城县29.09 t·hm^(-2),其次为牡丹区28.94 t·hm^(-2)。畜禽粪便通过不同处理方式和收集工艺处理后,其总氮、总磷最终产生量分别为2.66万t、1.08万t。平均单位耕地面积畜禽粪便氮、磷养分负荷分别为34.60 kg·hm^(-2)、14.11 kg·hm^(-2),均未超过欧盟粪肥年施氮和年施磷限量标准。总的来说,2022年菏泽市主要畜禽粪便产生量对有效耕地面积存在一定的污染风险,需要引起重视。To further understand the current pollution status of arable land in Heze City caused by livestock and poultry manure,based on the Livestock and Poultry Farming data from the‘2023 Heze Statistical Yearbook’,we used pollution discharge coefficients to estimate indicators such as the production of livestock and poultry manure and the agricultural land load in Heze City in 2022.The results indicate that the total emission of livestock and poultry manure in Heze City in 2022 was approximately 15.5773 million t,ranked by annual manure production as follows:pigs>poultry>sheep>cattle.The average agricultural land load in Heze City in 2022 was 25.21 tons per hectare(t·hm^(-2)),classified as level III according to the warning threshold.Yuncheng County had the highest agricultural land load in the city at 29.09 t·hm^(-2),followed by Mudan District at 28.94 t·hm^(-2).After treatment through various processing and collection techniques,the final production of total nitrogen and total phosphorus from livestock and poultry manure was estimated to be 26600 t and 10800 t,respectively.The average nutrient load of nitrogen and phosphorus from livestock and poultry manure per unit of agricultural land area was 34.60 kg·hm^(-2) and 14.11 kg·hm^(-2),respectively,both below the EU limits for annual application of nitrogen and phosphorus in fertilizers.In general,the main livestock and poultry manure production in Heze City in 2022 has a certain pollution risk on the effective cultivated land area,which needs to be paid attention to.
