摘要
在构建农业面源氨氮减排指标体系及介绍排放量计算方法的基础上,以黑龙江松花江流域为例,估算了“十二五”期间该地农业源氨氮排放量,结果表明:畜禽养殖和农村生活是氨氮污染的主要来源,排放量分别占35.33％和35.52％;以农田种植的氨氮入河量最大,占45.31％,农村生活的氨氮入河量最小,仅占8.36％.最后通过分析其减排能力,从加强规模化畜禽养殖污染治理,科学合理施用化肥,加大水土流矢治理力度,加强农村环境综合整治几方面提出了控制氨氮污染的对策.
Abstract
Based on establishing the reduction system of agricultural non-point source ammonia nitrogen pollution and introducing the emission calculation method,agricultural source ammonia nitrogen emission was introduced in the 12th Five-Year Plan period,with Songhua River basin of Heilongjiang Province as the research material.Result showed that livestock breeding and rural life were the main sources of ammonia nitrogen pollution,the emission accounted for 35.33％ and 35.52％,respectively.Farmland planting was the main source of ammonia nitrogen river pollution,accounted for 45.31％ ; but rural life has the minimum emission,occupying only 8.36％.Finally,by analyzing the pollution reduction capability,countermeasures were put forward,such as strengthening the management of large-scale livestock breeding pollution,scientific and rational application of fertilizer,enhancing the control of water and soil loss,and promoting the comprehensive improvement of the rural environment.
