摘 要 为了应对全球气候变暖,
中国政府提出到 2030 年CO2排放达到峰值(或峰值平台)
的减排目标.为了探究中国能否实现该减排目标,
本研究以江苏省为例,
基于长期能源规划替
代模型(LEAP) ,
耦合对数平均迪氏分解模型,
运用情景分析法科学设定快速、
中速、
慢速达峰
3种发展情景,
预测 CO2排放达峰时间及峰值水平.结果表明:2000—2015 年间,
经济规模效
应是 CO2排放总量增长的主要驱动因素,
其贡献度高达 147.4%;技术进步效应是最重要的缓
解因素,
贡献度为-60.4%,
一次能源结构效应、
产业结构效应、
人均收入效应、
人口规模效应
的贡献度分别为-5.3%、9.7%、11.0%、0.6%.在快速、
中速达峰情景下,
江苏省分别在 2025 和
2029 年达到 CO2排放峰值,
峰值分别为 7.01、7.95 亿t,
慢速达峰情景下未能实现 2030 年的
CO2排放达峰目标.综合研究分析,
江苏省有着较大的减排潜力,
经过相应的努力能够实现
CO2减排目标.为实现 2030 年的 CO2减排目标可采取以下措施:主动适应经济新常态,
稳定发
展增速;积极发展第三产业,
平衡经济结构;持续推进节能减排技术,
降低能源消费强度;大力
发展天然气及核电等清洁能源,
优化一次能源消费结构.

Abstract:China has put forward CO2emissions reduction target (committing to achieve CO2emis-
sions peak or plateau by 2030)to prevent global climate change. With Jiangsu Province as a case,
we explored whether China could achieve the 2030 CO2emissions reduction target. We predicted the
peak volume and time of CO2emission in three scenarios,i.e.,quick scenario,medium scenario,
slow scenario,respectively,based on the long-range energy alternatives planning system (LEAP)
model and the logarithmic mean Divisia index decomposition approach. The results showed that,
during the period 2000 to 2015,the economic scale effect was the most important driver,whose
contribution to the increase of total CO2emissions was as high as 147.4%. The technology progress
effect was the main mitigation factor for CO2emissions,which caused CO2emissions to decrease by
60.4%. In addition,the contributions of energy structure effect,industrial structure effect,per
capita income effect and population scale effect to CO2emissions were -5.3%,9.7%,11.0%,and
0.6% respectively. In quick and medium scenarios,the peak CO2emissions of Jiangsu Province
would be 701 million tons in 2025,and 795 million tons in 2029,respectively. In slow scenario,
however,Jiangsu Province could not achieve the 2030 CO2emissions reduction target. To achieve
the 2030 target,Jiangsu Province needs to adopt some strategies,including actively developing the
