ABSTRACT

This study was conducted to develop an allometric equation for Forsythia koreana and Syringa oblata var. dilatata, commonly planted in settlements, and to identify suitable variables for this model. F. koreana and S. oblata var. dilatata are widely planted across Korea and are used in landscaping and rooftop greening. The allometric equation is primarily based on growth characteristics such as tree diameter, height, and canopy area to estimate carbon storage. For F. koreana and S. oblata var. dilatata variables like diameter, height, and canopy width were measured. The plants were divided into sections (leaves, branches, stems, and roots) for biomass measurement. Using these measurements and carbon content ratios, carbon storage was calculated, and the importance and correlations of each variable were evaluated, with Root collar diameter identified as the primary variable. Height and canopy width also showed significant correlations in some indicators. The developed allometric equation achieved the highest explanatory DW=axb of the power form based allometric model. These findings can serve as foundational data for quantifying carbon storage in settlements and supporting national carbon neutrality policies.
