Study on Accounting Method and Model of Ammonia Emissions From Livestock and Poultry Breeding
摘要
Abstract
In China,livestock management practices are under constant pressure for minimizing their impacts on the environment.This study aims at summarizing the previous researches and finding a proper way for the accounting of livestock ammonia emission in China,with the hope to provide theoretical and realistic basis for livestock regional management and delicacy management.The methods based on N or total ammoniacal nitrogen (TAN) flow and the models adopted were listed.Advantages and disadvantages of each method or model were analyzed.The results from the methods based on TAN flow are more accurate than the results from the methods based on N flow at the regional level.For Animal Feeding Operations at the farm level,the process-based models are more suitable than those methods based on N or TAN flow.For a long time,ammonia emission accounting researches in China were focused on macro accounting at the regional level,and few methods or models were adopted at the farm level.Based on the reality,a new potential bottom-up ammonia emission accounting framework was elaborated for livestock production management in China.An integrated model based on the process-based model and regional statistic model was developed for livestock production management.Different parameters,such as feed,excrement feature and disposal technology,were sorted and divided into six categories.Different factors were illustrated according to the livestock production management reality.Further researches have been proposed in the aspects of improving the accuracy of the process-based modes,investigating the status for livestock production management,gathering data at the regional level,localizing the parameters,optimizing waste disposal technology,etc.关键词
