Driven by the carbon peak and carbon neutrality targets,how to follow the green and low-carbon approach to achieve carbon neutrality under the conditions of limited urban construction space and green space is a practical problem to be solved urgently.This study focuses on the carbon sequestration and oxygen release of plants at the scale of three-dimensional greening.Five categories and 74 species of plants suitable for three-dimensional greening in the Guanzhong region are selected,and their carbon sequestration and oxygen release capacity are estimated using green content as the calculation indicator,providing data reference for scientifically measuring the carbon sink of three-dimensional greening based on the full life cycle assessment of buildings.The order of carbon sequestration and oxygen release of five types of tree species is:ground cover plants>Arbour>Vines>Evergreen shrubs>Deciduous shrubs.Among the five types of tree species,the ones with the highest carbon sequestration and oxygen release are Mulberry,Sabina Vulgaris,Buddleja,Honeysuckle,and Dianthus Plumarius.Cluster analysis is conducted on the carbon sequestration and oxygen release of 74 plants,and a total of nine high carbon sequestration and oxygen release plants are selected.
