CH₄ Emissions Reduction Potential of Rice Paddy Ecosystem in South Jiangsu Province

Abstract:

Estimating the reduction potential of methane (CH₄) emissions in order to provide some advices for reducing them in paddy ecosystem. In order to study the temporal and spatial variation characteristics and the reduction potential of CH₄ emissions, conducting a database of CH₄ emissions of rice growing seasons and rice growing area in the study area. From 2001 to 2010, both the rice growing area and the CH₄ emission of south Jiangsu province shown a declining trend. In these 10 years, total CH₄ emissions decreased by 29.90×10¹⁰g, a drop of 30.72%. Base on the rice growing area in 2010, the total reduction potential of CH₄ emissions was 46.18×10¹⁰g in south Jiangsu province. From 2001 to 2010, the difference of CH₄ emissions per unit area between the cities were not big, their CH ₄ emissions reduction was mainly due to a reduction of rice growing area.
