| 摘要: |
| 城市是碳排放产生的主要地域空间，是进行“碳中
和”核算与政策制定的主体。除了减少固定能源与交通碳排放
外，增加城市碳汇也是实现“碳中和”的重要手段。通过分析
沈阳三环区域城市碳汇(植被、土壤、水系、建筑物)不同组
成部分的碳汇能力，估算出城市碳汇固碳量为430.93万t，
能够抵消沈阳市年能源消耗产生CO2的7.34%。在明晰城市
碳汇固碳机理、固碳潜力及其空间分布特征的基础上，提出增
加固碳面积与提升碳密度两方面的城市碳汇功能提升策略，旨
在为中国低碳规划与碳中和实现提供理论指导与技术支撑。 |

| Abstract: |
| Cities are the main geographical space where carbon
emissions are generated and the main body of "carbon neutrality"
accounting and policy formulation. In addition to reducing carbon
emissions from stationary energy and transportation, increasing urban
carbon sinks is also an essential method to achieve carbon neutrality. By
analyzing the carbon sink capacity of different components of the city's
carbon sinks (vegetation, soil, water system, buildings) inside the third
ring road area of Shenyang, it is estimated that the amount of carbon
sequestration in the city's carbon sink is 4.3093 million tons, which
can offset 7.34% of the CO2 produced by Shenyang's annual energy
consumption. Based on the carbon sequestration mechanism, carbon
sequestration potential and spatial distribution characteristics of the city's
carbon sinks, the strategies to improve the function of urban carbon sinks
are proposed from two aspects including optimization of spatial pattern:
increasing carbon sequestration area and increasing carbon density.
The aim is to provide theoretical guidance and technical support for the
realization of China's low-carbon planning and carbon neutrality. |
