摘　　要：文章利用灰色斜率关联度,对碳排放量与城市规模中的人口、经济和土地因素的关系进行了实证研究,结果表明人口与碳排放量存在一定正相关关系,随着人口规模的增加,新增人口的人均碳排放量高于存量人口;经济增长与碳排放量存在显著正相关关系,经济增长对碳排放变化具有增量效应:而土地开发密度与碳排放量存在显著负相关关系,土地开发密度越低,碳排放量越高。针对上述研究结论,提出了构建低碳南京的建议,以为低碳城市建设服务。This article uses degree of grey slop to analyze the relation between carbon emissions and the population, economic, land factor of urban scale. The result shows that there is a certain positive correlation between the population and the carbon emission, as the growth of the population, the carbon emission of the addition population is higher than the stock of the population. The relation between the growth of economic and carbon emission is a significant positive correlation, and economy scale has increment effect to carbon emission. However, the relation between the density of land development and carbon emission is a significant negative correlation, carbon emission increased when the density of tand development reduced. Finally the paper brings forward some suggestions to build the low carbon city in Nanjing and to serve the development of low carbon city.
