中国大陆CO人为源排放清单

Anthropogenic CO emission inventory of China's Mainland

在经济部门、燃料类型、燃烧方式/工艺技术3个层次对排放源进行划分的基础上,根据各类源的能源消耗/产品产量及相应的排放因子,建立了中国大陆2001年分省区CO人为源排放清单.结果表明,中国大陆2001年CO人为源排放量为1·5×108t.生物质、煤炭和汽油是CO排放的主要来源,分别占总排放的35·24%、31·67%和20·31%;CO主要来源于居民生活(32·15%)、工业燃烧(23·77%)和机动车排放(21·75%).CO排放的地区分布极不均衡,山东、河北、山西、辽宁等12个省区的年排放量在5·0×106t以上,集中了全国总排放的2/3;上海、北京和天津3市的年均排放强度最高(大于100t·km-2·a-1);而西藏、青海、新疆和内蒙古4个省区的CO排放强度均不足5t·km-2·a-1·

Anthropogenic CO emission by province of China's Mainland is estimated based on the three-level subsection split of economic section, fuel type and combustion process/technology by using the data of energy consumption/production volume and emission factor of each subsection. Anthropogenic CO emission of China's Mainland is about 150Mr in 2001. Combustions of biofuel, coal and gasoline are major sources of CO emission which take the fraction of 35.24 % ,31.67 % and 20.31% of the total emission respectively. Sectional emission is dominated by domestic combustion （32.15 % ）, industrial combustion （23.77%） and transportation （21.75%）. Remarkable imbalance of CO emissions by provinces can be seen that CO emissions in 12 provinces such as Shandong, Hebei, Shanxi and Liaoning exceed 5Mr, the total of which account for 2/3 of total emission of China's Mainland. Regions with highest CO emission intensities are Shanghai, Beijing and Tianjin （ 〉 100 t· km^- 2· a^- 1 ）, while CO emission densities in Xizang, Qinghai, Xinjiang and Inner Mongolia are lower than 5 t· km^- 2· a^- 1）.
