| Abstract: |
| 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 |
