【摘要】 利用排放因子法,以昆明市主城区有代表性的生态居住小区为研究对象,分析生态居住小区内人口呼吸碳排放、交通碳排放、化石能源使用碳排放、居民用电碳排放、居民用水碳排放5个主要的人类活动碳源排放特征,对比不同居住小区之间的碳排放差异,并提出节能减排措施。分析得出:小区之间碳排放总量差异较大;相同碳源碳排放量在各小区总碳排放量中比例差异较小;小区之间人均碳排放量差异不大;居住小区人口密度与单位面积的碳排放量成正比例关系。更多还原

【Abstract】 By using the emission factor method,this paper taking the representative ecological residential area in the main city of Kunming as the research object,analyzes the carbon emission characteristics about the population respiratory carbon emissions、traffic carbon emissions、fossil fuels use carbon emissions、residential electricity carbon emissions、residential water carbon emissions of the five main human activities and compares the carbon emission differences between the different residential communities and put forward energy-saving emission reduction measures. The results showthat the total carbon emissions among the communities are quite different; the proportion of carbon emissions in the same carbon source is smaller than that in the total carbon emissions of the communities; the per capita carbon emissions between the communities are not different; the population density of the residential area is proportional to the carbon footprint per unit area.更多还原
