spatial-temporal characteristics and decoupling effect of carbon emissions in the major pig producing areas in china

Abstract

The major pig producing areas have made an important contribution to the development of animal husbandry economy in China, but the intestinal fermentation of pig breeding and its excreta are important sources of greenhouse gas emissions. Based on the data,this article compared the effect of carbon emissions in the major pig producing areas from 2004 to 2014. The results showed that carbon emissions of pig producing presented obvious characteristic of "up-down-up". On the contrary, the indensity of carbon emission showed the characteristics of "down-up-down" and the regional difference was very clear. At the same time, the relationship of carbon emissions of pig producing and economic development mainly showed ideal weak decoupling during the study period. Finally, some advices of promoting low-carbon farming was given.
