摘要
土地利用变化与碳排放密切相关。运用相关统计数据,依据碳排放模型、碳足迹模型、K-均值聚类法,测算并分析了安徽省不同土地利用方式下的碳排放状况及时空变化。结果表明,2001~2010年安徽省碳排放主要有以下特点：1）碳净排放量逐年递增,建设用地占总排放的95%以上。2）能源消费碳足迹总体增加,生态赤字不断扩大。3）各市碳排量差异显著,地域分配不均。
The land use patterns are closed to carbon emissions. Base on the statistical data and carbon emission model,carbon footprint model, K-means clustering method, calculation and analysis the spatial-temporal difference of carbon emissions on different land use patterns in Anhui province. The results shows that,From 2001 to 2010 , the carbon emissions in Anhui province have such characteristics：1）The carbon emissions increased year by year, about 16.63 % annual. The carbon emissions in construction land accounted for more than 95 % , in cultivated land was decreased and then increased on 2005.2） The carbon footprint of energy consumption was increased, the ecological deficit was widening. 3）The carbon emission has a significant geographical differences of each city,the distribution is not balanced
