摘　　要：基于化肥、农药、农膜、农用柴油、灌溉、翻耕六个主要农地利用碳源,从时间、空间两个维度对湖北省农地碳排放量进行估算。结果表明,在时间尺度上,历年农地碳排放总量呈逐渐缓慢上升趋势,历年单位面积农地投入品使用量始终保持稳定;在空间尺度上,农地碳排放空间差异明显,湖北省各地、州、市农地利用碳排放总量、碳排放强度存在较明显差异,其中,襄阳、黄冈、荆州分别位列碳排放总量前3位,鄂州、随州、襄阳分别位列碳排放强度前3位。Based on agricultural statistical data,this paper estimated the carbon emission from six kinds of main carbon sources like chemical fertilizer,pesticide,farming film,agricultural diesel,irrigation and cultivate during agricultural land-using in Hubei Province from the spatialtemporal aspect.The results show that,during the period 2000-2010,the agricultural carbon emission load in Hubei Province presents gradual upward trend.From spatial-changing aspect,the carbon emission amount and emission intensity have obvious difference,in which,Xiangyang,Huanggang,Jingzhou are the places which stands at the first three ones of the high-emission-amount,besides these,Ezhou,Suizhou,Xiangyang are the first three ones of the high-emission-intensity.
