| 摘 要： | 在确定畜禽粪便年排放量的估算方法和畜禽粪便排泄系数的基础上,根据2012年大庆市畜禽养殖数据和耕地面积,估算大庆市畜禽粪便产生量及其主要养分含量,并对畜禽粪便耕地消纳负荷情况进行分析评价.结果表明,2012年大庆市畜禽粪便总排放量约为710.45万t,其中以牛和生猪排放量最高,分别占48.1%和29%.农田畜禽粪便负荷量平均为9.45 t·hm-2,农田N、P养分负荷量平均为57.8 kg·hm-2和17.96 kg·hm-2,大庆市各县区耕地对畜禽粪便仍有消纳能力,畜禽养殖业发展仍有环境空间. |

| Abstract: | Based on pre-selected method for predicting annual emission of animal excrement and the excretory coefficient of animal excrement, the consumption and loads of the ccultivated land of animal's excrement was analyzed and evaluated according to the data of animal's breed aquatics and contents of the major nutrients.Results show that in 2012, the total produced excrement of Daqing's animal was about 7,104,500 tons, pigs and cow accounting for 48.1% and 29% respectively.The average load of animal excrement on farm was 9.45t·hm-2.The N and P average load was 57.8 kg·hm-2 and 17.96 kg·hm-2.Many counties' cultivated land was able to consume animal's excrement and the breeding industry of animal still had environment spaces. |
