Abstract

This study aim to reveal the spatiotemporal dynamics and trends of carbon storage in in Taiyuan City’s ecological public forests and to assess their carbon sink potential.The findings provide scientific basis for the sustainable regional forests management and the enhancement of carbon sink functions.The ecological public forest inventory resource data of Taiyuan City in 2018 and 2023 were used to estimate carbon storage using a stand biomass model.The carbon storage,carbon density and carbon sink characteristics of different tree species,forest origins and age groups were analyzed.Furthermore,a Logistic empirical model was employed to simulate the dynamics of carbon storage and predict its future sink potential.The results showed:1) From 2018 to 2023,the total carbon storage of ecological public forest stands increased from 2.24 Tg to 3.14 Tg.Middle-aged forests contributed the most to carbon storage,with Pinus tabulaeformis and Quercus spp.having the highest values.2) The carbon density of natural forests is higher than that of planted forests.Among all species,Picea asperata,Larix principis-rupprechtii,and Betula L.exhibited the highest carbon densities.3) Projection indicate that the total carbon storage of ecological public forest stands in Taiyuan City will reach 7.21 Tg by 2060,4.07 Tg increase from 2023.The high proportion of young and middle-aged forestssuggests significant future carbon sink potential.Theoverallcarbon storage of ecological public forests in Taiyuan City shows an increasing trend.By adjusting and optimizing the age structure of forests,it is helpful to improve forest quality and further increase carbon storage and overall carbon sink capacity.Protecting and enhancing existing forest resources and improving forest quality are a key strategy for promoting carbon sequestration.

Key words： ecological conservation forest; carbon storage; carbon sink; dynamic
