Abstract 城市作为主要的人为碳排放源受得广泛关注,然而涉及城市绿地的碳排放和固碳功能未得到充分的重视。文章对近年来城市绿地研究现状进行了综述,主要从城市绿地碳库及通量的概念模型植被碳库、土壤有机碳库、微生物量碳和黑碳碳库几个方面展开论述,认为高大的乔木是城市绿地植被碳库的主体,而群落类型、城市功能区和绿地年龄强烈地影响着城市植被碳库的大小;城市绿地土壤有机碳储量一般高出植被碳储量数倍,而市区的土壤碳密度一般高出郊区和乡村;城市绿地土壤有机碳、微生物量碳和黑碳的数量受植被类型、城市功能区、土地利用和土层的影响明显。建议今后应加强城市绿地植被的碳库动态的长期定位监测;深入研究城市各种人为干扰活动对土壤碳库的影响机理;建立高度空间异质性的城市环境下植物和土壤取样的方法体系。

[Objective]This study analyzed the domestic and foreign research progresses of carbon storage in urban green space in order to provide useful references for future carbon cycle researches in urban green space. [Method]Along with literary analysis, the green space carbon storage and flux conceptual model was constructed in order to study carbon researches from recent years, including urban greenbelt vegetation carbon storage, soil organic carbon pool, micro-biomass carbon, and black carbon. [Result ]The results showed that large arbor trees were the major contributors to the vegetation carbon storage, which were markedly affected by the plant community coenotype, the urban functional area, and the green space age. In general, the organic carbon storage in urban green space was se
