| 摘 要： | 城市绿地建设具有工程建设“碳排放”和植物光合“固碳”双重特征，是实现“碳减排、碳增汇”的主要途径。传统绿地的建设注重景观而忽略生态，植物配置不合理，追求快速成景，改造频繁且未妥当处理园林绿化废弃物，不但降低了植物光合固碳，而且增加了建设碳排放。在“碳达峰、碳中和”背景下，绿地建设应综合考虑碳减排、碳增汇，减少硬景工程、增加绿量，优化植物配置，优选本地低碳材料和适龄苗木，利用自然塑造地形，精细施工，避免频繁改造，并推进园林绿化废弃物资源化利用，以满足生态文明建设和应对气候变化的新需求。

| Abstract: | Urban green space construction can produce carbon emissions during construction and promote carbon sequestration through plant photosynthesis, which is the main measure for reducing carbon emission and enhancing carbon sink. Landscaping are more important than ecological traits during traditional green space construction, resulting in more carbon emissions and less carbon sequestration, owing to unreasonable plant configuration, rapid landscaping, frequent converting and upgrading, and improper treatment of greening waste. In the context of carbon peaking and carbon neutrality, green space construction should consider comprehensively carbon emission reduction and carbon sink increase, including reducing hard landscape, increasing green quantity, optimizing plant configuration, selecting preferentially local low-carbon materials and age-appropriate seedlings, reshaping terrain, naturally constructing finely, avoiding converting frequently, and promoting to reutilization of greening waste, so as to meet the new needs of ecological civilization construction and coping with climate change. |
