摘要
为了解重庆直辖以来经济发展与碳排放量之间的相互关系,以重庆市直辖以来1997—2008年为研究时间段,对重庆市经济发展与碳排放量进行了相关性分析研究。研究时间段内重庆市碳排放总量增加了2.43倍,碳排放增长变化过程分为两类:波动下降阶段(1997—2000年和2005—2008年);稳定上升阶段(2000—2005年)。对碳排放量变化与经济总量、能源结构、产业结构、能源使用效率进行相关性分析,结果表明,碳排放量一般会随着经济总量的增大而不断增长,其中煤炭消费量对碳排放总量的贡献率最高,平均贡献率为79%,占主导地位;第二产业中对减排的贡献主要体现在能耗强度的降低上,能耗强度降低对碳排放总量的减少,具有至关重要的作用;今后产业结构调整的重点应放在第二产业(特别是建筑业)以及第三产业,着重提高其中的能源使用效率。研究认为,重庆市未来减排的主要途径是优化能源结构,提高清洁能源的比重;优化产业结构,降低能耗;改善能源消费结构,提高使用效率;增加植被覆盖,提高土壤固碳能力;倡导低碳生活,构建低碳社会;完善政策法规体系,加强管理。
In order to research the relationship between the economic development and the carbon emissions since Chongqing municipality directly under the Central Government. Take 1997--2008 to research the correlation of economic development and carbon emissions in Chongqing. In this period carbon emissions has increased 2.43 times and growth change process is divided into two categories ： volatility drop stage during （1997--2000） and （2005--2008） ; steady rise stage during （2000--2005）. To analyze the carbon emissions change and economic output, the energy structure, industrial structure, and efficient use of energy resources, the results show that ： carbon emissions will generally increase with economy, among them the coal consumption on the contribution of carbon emissions is the highest and dominant, average contribution rate is 79%. In the second industry, the emission of work is reflected in energy consumption, the reduction in energy consumption has important role in the decrease of carbon emissions. In the future, industrial structure adjustment should focus on the second and third industry and construction, improve the industry on energy efficiency. The main way to reduce the emissions of the future is to optimize the energy structure, raise the proportion of clean energy ; to optimize the industrial structure and reduce the energy consumption; to improve energy consumption structure and raise the use efficiency; to increase vegetation cover, and improve soil carbon sequestration ability; to advocate low carbon life and build low carbon society; to improve policy and regulations system and strengthen management.
