The Ideas on Survey Methods for Monitoring of Ammonia Emission Coefficient in Livestock and Poultry Breeding

Ammonia from livestock and poultry farming is included in the second national census of pollution sources as an agricultural pollutant for the first time. However, due to the late start of ammonia emission control in livestock and poultry breeding, the ammonia emission coefficient has not been determined according to the characteristics of livestock production in China. Based on the principle of precise management and comprehensive summary for the work experience of the first time pollution census of livestock and poultry breeding pollution emission coefficient, it puts forward structure and type of livestock farming ammonia emission coefficient, as well as the layout and methods of field monitoring points. At the same time, on the basis of China's animal husbandry production and the key factors influencing the in-depth analysis of livestock and poultry ammonia emissions, it puts forward the idea for monitoring the ammonia emission coefficient distribution which meets the requirements of both geographical division and climatic division, and establishes the monitoring calibration method of livestock and poultry emission coefficient per unit standard for the first time. This method not only reflects the emission differences of different regions within each district, but improves the spatial resolution of the coefficient, eliminates the problem of large coefficient difference between adjacent districts and counties in different regions, simplifies the report design, improves the accuracy of ammonia emission accounting effectively, and can provide effective technical support for the monitoring of ammonia emission coefficient of livestock and poultry in the second national census of pollution sources.
