规划设计实践视角下城市绿地碳汇与碳排研究成果可用性述评

A Review of the Usability of Research Results on Carbon Sink and Carbon Emission in Urban Green Space from the Perspective of Planning and Design Practice

城市绿地的增汇与减排功能是中国“碳中和”目标在城市人居环境领域的重要实现路径。在2008-2021年的研究进程中,学者们针对城市绿地碳汇与碳排进行了大量基础研究。为探明规划设计实践视角下现有研究的成果可用性,从理论体系、清单数据、影响关系以及策略方法4个层面并结合不同维度对城市绿地碳汇与碳排研究成果进行交叉分类分析。结果表明:(1)理论体系研究成果现已融合交叉学科内容不断更新,但总体进程较缓;(2)清单数据研究成果中部分研究内容缺乏规范化的核算边界;(3)影响关系层面,当前研究成果在多维度的影响因子证据链方面具有提升空间;(4)当前策略方法的研究成果具有较强针对性,但有待验证其实际有效性。总体上针对现有城市绿地碳汇与碳排相关研究成果进行了有效回顾与归纳,进一步指出规划设计实践视角下未来有待深入的研究发展方向与内容,基于研究成果可用性为城市绿地在低碳方面的研究厘清思路。

The function of increasing sinks and reducing emissions of urban green space is an important way to achieve the“carbon neutrality”goal of China in the field of urban human settlements.During the research process from 2008 to 2021,scholars conducted a lot of basic research on carbon sequestration and emission in urban green spaces.In order to explore the usability of existing research results from the perspective of planning and design practice,this paper conducts a cross-classification analysis of the research results of urban green space carbon sequestration and emission from the four levels of a theoretical system,inventory data,impact relationship,and strategy and method combined with different dimensions.The results show that:(1)The research results of the theoretical system have been continuously updated with the integration of interdisciplinary content,but the overall process is slow;(2)Some research results in the inventory data research results in lack standardized accounting boundaries;(3)The current research results at the impact relationship level have an improvement in the multi-dimensional impact factor evidence chain;(4)The research results of strategies and methods have strong pertinence,but their actual effectiveness needs to be verified.In general,this paper effectively reviews and summarizes the existing research results related to carbon sink and carbon emission in urban green space,further points out the future research development direction and content from the perspective of planning and design practice,and clarifies the ideas for the research on low-carbon aspects of urban green space based on the availability of research results.
