| 摘 要： | 基于碳平衡理论,通过综合分析城市区域内主要自然生态系统的固碳功能,以及主要社会经济活动的排碳行为,构建了城市碳平衡分析模型,并以昆明市为例进行了研究。结果表明:昆明市碳收支不平衡,碳汇对碳源的抵消作用很弱;并且随着社会经济的发展这种不平衡状况在加剧,2010年,昆明市碳平衡系数为1.90,即城市释碳量是固碳量的1.90倍;碳供需余缺(释碳量-固碳量)达到1565.35×104t/a。产值增长是碳排放增加的主要动力,而能源强度下降、能源结构和产业结构调整是减缓碳排放的主要动力。

| Abstract: | Based on the carbon balance theory and detailed investigation date, this paper calculated the major car- bon emission of socioeconomic activities and the carbon sequestration of remnant natural ecosystem to estimate the carbon source and carbon sink in a complex urban ecosystem of Kunming city during 2008 -2010. The results showed that the input and output of carbon are not keep balance in Kunming City during the investigated period. In addition, the unbalance was aggravating with the rapidly urban development. In 2010, the amount of carbon emission was 1.90 times of the carbon sequestration. The difference between carbon emission and carbon sequestration is 1565.35 × 104 t/a. Industrial output growth topped other factor to be the most important driving force for carbon emission increase, while energy intensity decline, energy structure and industrial structure adjustment were factors to mitigate carbon emissions. |
