The main conclusions are as follows: 1) Total anthropogenic carbon emission of Nanjing increased from 1.22928 x 107 t in 2000 to 3.06939 x 107 t in 2009, in which the carbon emission of Inhabitation, mining & manufacturing land accounted for 93% of the total. 2) The average land use carbon emission intensity of Nanjing in 2009 was 46.63 t/ha, in which carbon emission intensity of Inhabitation, mining & manufacturing land was the highest(200.52 t/ha), which was much higher than that of other land use types. 3) The average carbon source intensity in Nanjing was 16 times of the average carbon sink intensity(2.83 t/ha) in 2009, indicating that Nanjing was confronted with serious carbon deficit and huge carbon cycle pressure. 4) Land use area per unit GDP was an inhibitory factor for the increase of carbon emissions, while the other factors were all contributing factors. 5) Carbon emission effect evaluation should be introduced into land use activities to formulate low-carbon land use strategies in regional development.展开更多
本文分析了1997—2008年间浙江省能源消费碳排放数据,采用对数均值迪氏分解(Logarithmic Mean Divisia In-dex,简称LMDI)法,对能源消费导致的二氧化碳排放量和碳排放强度进行结构分解。结果表明,浙江省能源消费碳排放量不断增加是由人...本文分析了1997—2008年间浙江省能源消费碳排放数据,采用对数均值迪氏分解(Logarithmic Mean Divisia In-dex,简称LMDI)法,对能源消费导致的二氧化碳排放量和碳排放强度进行结构分解。结果表明,浙江省能源消费碳排放量不断增加是由人口和人均国内生产总值(GDP)因素引起的,其中人均GDP增长是碳排放量增加的主要因素;能源强度下降是降低二氧化碳排放量的主要因素,能源结构的作用呈现波动性,且程度较小。本文得出如下结论,要减缓二氧化碳的排放量,构建"低碳浙江"、"生态浙江",应从重新认识人均GDP、控制人口数量、调整能源结构、降低能源强度、提高能源效率等方面考虑。展开更多
