| Abstract: |
| Livestock manure is an important source of greenhouse gas emissions. Different manure management methods have a significant impact on greenhouse gas emissions. Scientific analysis changes in greenhouse gas emissions and their influence of manure management will improve manure management methods, promote manure recycling use, and achieve low-carbon animal husbandry in China. This article analyzed the changes in greenhouse gas emissions from livestock manure management sector of China national communications report from 1994 to 2014. The result showed that the proportion of greenhouse gas emissions from this sector in China had gradually increased from agricultural sources, and the proportion reached 17.7% in 2014. Based on the data from the first and the second China pollution source censuses, the result showed that the main manure collection method was solid manure collection and the manure was mainly applied to field after solid storage, liquid storage and anaerobic digester. This study also compared and analyzed the impact of different manure collection processes and changes in manure management methods on greenhouse gases emissions, and proposed a full-chain technology innovation proposal through source reduction-process control-end use way, to promote animal husbandry low-carbon and green development. |
