Abstract:

Based on six kinds of mainly carbon source,such as chemical fertilizer,pesticide,farming film,agricultural diesel,tilling and paddy field,the research calculated the amount of agricultural land use carbon emission in Hubei Province during the period of 1995-2009, as well as 16 cities of Hubei Province in 2008.The results showed that the agricultural land use carbon emission and carbon emission intensity in Hubei Province presented threestagecharacteristic，namely “risedeclinerise”.The regional difference was very obvious.The amount of agricultural land carbon emission in Jianghan Plain and northeast of Hubei Province was high,while in west and southeast was low;the agricultural land use carbon emission intensity in east of Hubei Province was the highest,followed by middle zone,and the west zone was the lowest.Further more,the decoupling relationship between agricultural land use carbon emission and agricultural economic development was analyzed by Tapio decoupling model,and the results indicated that the relationship mostly were weak decoupling and strong decoupling.Thus,it’s easy to know that land use carbon reduction achieved certain results in recent years
