Baseline carbon sink monitoring of the 2023 land greening pilot demonstration project in Hengyang City
Based on the methodology of afforestation carbon sinks and forest management carbon sinks,the baseline carbon sinks of the 2023 land greening pilot demonstration project area in Hengyang City,Hunan Province were monitored by means of stratified sampling,typical sampling,and standard site investigation.Through calculation,the estimated baseline forest biomass carbon sink in the project area at the survey time point from December 20,2023 to January 23,2024 was 904.5 thousand tons.Within the project boundary of artificial afforestation and restoration of degraded forests mainly composed of young forests,the baseline carbon storage was relatively low.The carbon sinks of young forests of mixed forests,Chinese fir,and slash pine were 56.99％,56.83％,and 37.77％of the near-mature/mature/over-mature forests with the same dominant tree species,respectively,and there was a significant space for carbon sink growth in the future.Compared to the other tree species,the artificial management intensity of Chinese fir forests was relatively high,and had greater potential for carbon storage growth.Conducting baseline carbon sequestration monitoring can lay a solid foundation for monitoring the carbon sequestration increment of the Hengyang land greening pilot demonstration project,and provide scientific basis for evaluating the project's performance in improving the carbon sequestration capacity of the forest and grassland system.
