Integrated Analysis of Methane Emissions on in Rice Paddy Field of South Jiangsu Province

Abstract:

Field experimental results about methane (CH₄) emissions of rice growing seasons were analyzed in south Jiangsu province from 2001 to 2010. In order to study the temporal and spatial variation characteristics, conducting a database of CH₄ emissions of rice paddy field in the area. On the spatial distribution, Zhenjiang city had the highest CH₄ emission flux in rice growing season of this area, up to 7.80g/(m²h). Amount of CH₄ emissions per unit area in Changzhou city was slightly higher than other cities, up to 17.17g/m². From 2001 to 2010, both the rice growing area and the CH₄ emission of south Jiangsu province shown a declining trend during last decade. The rice growing area declined 170670 ha, a drop of 28.81%; total CH₄ emissions decreased by 29.90×10¹⁰g, a drop of 30.72%. From 2001 to 2010, there was no significant difference of CH₄ emissions per unit area between the cities, all CH₄ emissions reduction was mainly due to a reduction of rice growing area.
