| 摘 要： | 水泥工业是温室气体二氧化碳(CO2)的主要排放源,利用碳排放数学模型计算2001-2010年我国水泥工业碳的排放量,分析碳排放量的变化特点和发展趋势。结果表明:水泥工业碳排放总量逐年增长,与水泥产量和排放强度呈线性关系。"十一五"期间单位产品碳排放强度由0.69 t/t下降到0.65 t/t。万元GDP碳排放量2008年达到最低值为0.295 1 t,平均每年万元GDP碳排放量下降2.85%。水泥工业十年间实施节能降耗、资源循环利用、提高经济效益等措施,对于减少碳排放具有明显效果。

| Abstract: | Cement industry is a major source of greenhouse gas-carbon dioxide(CO2)emission.Mathematical model was used to calculate carbon emission quantities for China’s cement industry during 2001 to 2010,and change characteristics and trend for carbon emission with cement outputs and emission factors were analyzed.Results indicated that carbon emissions quantities increased rapidly every year,and there is a linear relationship between carbon emission quantities and cement output,emission factors.Carbon emission factors decreased from 0.69 t/t to 0.65 t/t during the 11 th Five-Year-Plan period.Carbon emission quantities of ten thousand Yuan GDP decreased to minimum 0.295 1 t in 2008,decreased by 2.85%.Results showed that the energy saving and resource recycling and increase of economic efficiency are appearing in the reduction of carbon emissions. |
