Calculation and Optimization of the Carbon Sink Benefits of Green Space Plants in Residential Areas: A Case Study of Suojin Village in Nanjing

Objectives: In the “dual evaluation” of land space, evaluation importance ecosystem service functions and residential areas is important, playing a significant role in plants acting as carbon sinks thereby achieving transformation low-carbon settlements. Methods: The paper compares analyzes five models for quantifying sink benefits focuses on national tree benefit calculator (NTBC) model, which suitable sequestration areas, to (i) estimate compare economic brought by trees shrubs (ii) analyze reasons differences between current data next 20 years, (iii) comprehensively evaluate technical points related plant landscape assess whether they comply with “Green Settlement Standard.” index system was scored according standard. Result: collected existing include following: When are good condition, order their year Zelkova serrata > Cedrus deodara Sapindus saponaria Sophora japonica Cinnamomum camphora Prunus cerasifera Magnolia grandiflora Ulmus pumila Acer L. Lagerstroemia indica Sapium sebiferum Sabina Punica granatum palmatum Celtis sinensis Pers Bambusa multiplex Cycas Melia azedarach Pinus parviflora, that years Thunb Broussonetia papyrifera parviflora. gain Photinia beauverdiana Pittosporum tobira Ligustrum lucidum Viburnum odoratissimum Buxus cephalantha, cephalantha odoratissimum. Conclusion: Using plants, construction ideas, community structure maintenance estimation should be updated three aspects promote quantification green urban settlements development China.
