Dynamics of biomass and carbon sequestration across a chronosequence of Caragana intermedia plantations on alpine sandy land

Abstract Considering the variations in carbon concentrations among different plant components can significantly improve carbon storage estimates. The aim of this study was to estimate the biomass and carbon storage and sequestration in Caragana intermedia Kuang et H. C. Fu plantations for six differ...
