摘　　要：在“双碳”目标的驱动下,如何遵循绿色低碳途径在城市有限绿地空间条件下实现碳中和,提升城市绿地植物固碳效益成为新时代植物景观营造必须思考和解决的科学问题。结合西安地区不同土地利用类型下的碳储量时空变化状况,提出符合场地生境斑块连通性需求的4种城市绿色空间碳汇矩阵单元,探索植物碳汇在景观全生命周期中的设计过程。通过对西安地区典型绿地样方的持续调研观测,结合i-Tree软件总结出常见乔灌、地被植物的年固碳量,筛选出高固碳型植物种类,总结出适用于公园绿地和居住区绿地的高固碳型灌丛-地被型、地被型植物群落设计模式。依托“高固碳型植物群落数字化平台”对灌丛-地被植物群落碳汇效益进行持续智能监测与模拟,为植物种植设计方案优化和科学决策提供依据。Driven by the carbon peak and carbon neutrality targets,under the condition of limited urban green space, how to follow the green and low-carbon path to achieve carbon neutrality and improve the carbon sequestration benefit of urban green space plants has become a scientific problem that must be considered and solved in the construction of plant landscape in the new era. Based on the spatio-temporal variation of carbon storage under different land use types in Xi’an, four carbon-sink matrix elements of urban green space were proposed in accordance with the requirements of patch connectivity of site habitat, and the design process of plant carbon sink in the whole landscape life cycle was explored. Based on the continuous investigation and observation of typical green plots in Xi’an, the annual carbon sequestration amount of common trees, shrubs and ground cover plants was calculated with i-Tree software, and the species of high-carbon sequestration plants were screened, and the design patterns of high-carbon sequestration shrub-ground cover and ground cover plant communities, which were suitable for park green space and residential green space,weresummarized. Based on "The Digital Platform of High Carbon Sequestration Plant Community", continuous intelligent monitoring and simulation of carbon sink benefit of shrub and ground cover plant community were carried out, providing a basis for the optimization of plant planting design and scientific decision making.
