| Based on five aspects including chemical fertilizers, pesticides, agricultural films, agricultural machinery
and agricultural irrigation, which led to carbon emissions, using carbon emissions coefficient method to measure the carbon
emissions and strength of Jiangxi province during the period 1995-2011 and carbon emissions and strength of 11 districts
in 2010. Results showed that, from 1995 to 2011, carbon emissions in Jiangxi province presented increasing trend year by
year, farm land use carbon intensity showed firstly enhanced and then weakened trends, fertilizer and agricultural
mechanization was the main sources of carbon emissions at all kinds of agricultural activities. From the point of regional
difference in Jiangxi, carbon emissions of Ganzhou was in the first place in 2010, its carbon emissions relating to the last
was nearly 8.13 times; The carbon emissions intensity of Xinyu was the first, up to 7.4657 t/hm2, while the lowest was
Jingdezhen, only 1.9240 t/hm2, only 1/3 of Xinyu, seven major grain producing areas whose carbon emissions were at the
top were the main source of farm land use carbon emissions in Jiangxi province. On this basis, this paper used Tapio
decoupling model to analyze the decoupling relationship between farm land use carbon emissions and agricultural economic
development in Jiangxi province. The results showed that
from 1996 to 2011, the main decoupling relationships
between farm land use carbon emissions change and the
agricultural economy development were weak decoupling,
expansive connection, expansive negative decoupling,
presenting Jiangxi province gave priority to agriculture
economic development in recent years, performed poorly
in the environment effect. |
