Carbon Density Analysis and Model Structuring of Chinese Fir Forest:A Case Study of Suichang,Zhejiang Province
To explore the carbon sequestration and carbon sink enhancement management techniques of Chinese fir plantation,the carbon content and carbon density of different organs in different age stages and different densities of Chinese fir plantation in Suichang County were studied,and the car-bon storage prediction models of different organs were also constructed.Results showed that the average carbon content of Chinese fir forests was 50.15%,with the crown having the highest carbon content(51.59%).The carbon content in 25-year-old forests was significantly lower than in 32-year-old and 47-year-old stands,whereas stand density had no significant effect on carbon content.Average carbon density increased with stand age,while the effects of stand density on carbon density were primarily observed in older forests.Notably,medium density stands exhibited the highest carbon density in both the crown and trunk.The constructed carbon storage models for entire stands,trunks,crowns,and roots achieved R2 values above 0.9,indicating excellent model reliability.Our results showed that appropriate management density can help increase the carbon storage of Chinese fir plantation and enhance their carbon sink capacity.
