摘要
城市化区域是CO_(2)等温室气体的主要排放来源。城市绿地作为城市范围内唯一直接增汇、间接减排要素,精准监测其碳汇能力、分析其影响因素,能直观反映城市绿地的碳中和作用,这对增强城市绿地碳汇功能,促进城市低碳发展具有重要意义。研究梳理了多种城市绿地碳汇计量监测方法,主要有样地清查法、同化量法、微气象法、遥感估测法等,分析前人运用上述方法对不同尺度、类型城市绿地进行碳汇计量的研究成果,总结各方法的适用范围与尺度、优势与不足。在此基础上,针对城市绿地特征提出了不同尺度、不同方法相结合的城市绿地碳汇计量监测思路与框架,以期推进城市绿地碳汇的精确评估,为城市精细化管理、碳中和目标的实现提供理论和技术支撑。
The urbanized region is a major source of CO_(2) and other greenhouse gases.Urban green space is the only element in the city to increase carbon sequestration directly and reduce emission indirectly.Monitoring the carbon sequestration of urban green space accurately and analyzing its influencing factors,can intuitively reflect the carbon neutralization of urban green spaces,which is of great significance to enhance carbon sequestration function of urban green space and promote urban low-carbon development.In this paper,the various methods of carbon sinks measurement and monitoring in urban green space are sorted out,mainly including sample inventory,photosynthetic rate integration,micrometeorology evaluation and remote sensing estimation.This paper analyzes the previous research results of carbon sink monitoring on different scales and different types of urban green space,and summarizes the applicable scale,advantages and disadvantages of these methods.For the characteristics of urban green space,this study put forward the framework of measuring and monitoring urban green space carbon sinks with different scales and different methods to promote the precise assessment of urban green space carbon sinks,and provide theoretical and technical support for the implementation of urban refined management and carbon neutrality.
