    园林绿化工程施工阶段碳足迹研究——以武汉光谷大道隙地绿化工程为例

    Key words:landscape architecture; landscaping works; construction process; carbon footprint; carbon sink

    摘要:城市园林绿地是城市中唯一具有碳汇功能的绿色基础设施,但其自身的施工建设是否低碳值得关注。针对园林绿化工程施工阶段界定碳足迹的计算边界与计算思路,明确施工及其过程对碳排放有影响的因素,将其归结为“隐性”和“显性”2种碳足迹。结合武汉市光谷大道隙地绿化工程的施工工序解析碳足迹,并设计了低碳施工对比方案,提出:减少隐性碳足迹、合理选材、减少运输、科学养护4点措施,以实现城市园林绿地的“低碳”建设。

    Abstract:Urban green space is the green infrastructure with unique carbon sink function, and it is noteworthy to pay attention to its low-carbon construction. The paper studied the carbon footprint calculation edges and methods in landscaping green construction projects, and proposed factors categorized as "recessive carbon footprint" and "dominant carbon footprint" styles in it. Based on the landscaping works for the open space of the Optics Valley Road in Wuhan City, this paper calculated its carbon footprint in construction stages, then designed another lower carbon construction plan to contrast against the higher one. Finally, this paper concluded that carbon footprint could be decreased in landscaping works by 4 construction measures such as: 1) decreasing recessive carbon footprint, 2) selecting lower carbon materials, 3) reducing transportation, and 4) reasonable conservation, so as to realize the "low carbon" greening construction.
