中文摘要：

采用武汉市1996-2010年的土地利用变更数据、能源数据以及相关经济数据,通过构建碳排放、碳足迹模型,测算近15年来武汉市土地利用的碳排放量和碳足迹,并分析其碳排放量、碳足迹的变化及影响因素。结果表明,武汉市建设用地碳排放量占碳排放总量的98%以上,在1996-2010年处于逐年增加的状态,2010年已达到1996年的1.4倍;武汉市的总碳足迹和人均碳足迹也在逐年增加,碳赤字较为严重。碳排放总量的不断增加主要是由武汉市建设用地不断扩大以及经济增长方式和能源结构不合理造成。为此,武汉市不仅要控制建设用地的扩张,同时还应改变经济增长方式、调整能源消费结构。

英文摘要：

In order to build a ＂two sides society＂ and develop the low-carbon economy, the carbon emission and energy carbon footprint of Wuhan city during past 15 years were estimated. The changes and the impact factors were analyzed with carbon emission model and carbon footprint model based on data of land use patterns, data of energy and data of economic of Wuhan city from 1996 to 2010. The results showed that the carbon emission of construction land accounted for more than98% of total carbon emissions, and gradually increased from 1996 to 2010. Carbon emission of construction land in 2010 was1.4 times more than that in 1996. The total carbon footprint and per capita carbon footprint of Wuhan city increased constantly. Carbon deficit in Wuhan city was severe. The increase of total carbon emission was mainly caused by the increase of construction land and the growth way of the economic and the irrational energy structure in Wuhan. The expansion of construction land must be controlled. The growth mode of economy and the structure of the energy consumption should by adjusted.
