Carbon contents,biomass,carbon storage of different organs including leaf,branch,trunk,bark and root,and their distributions in Pinus armandii (HSS),Pinus yunnanensis (YNS),Keteleeria evelyniana (DYS),Quercus semicarpifolia (GSL)and Evergreen broad-leaf(CL)stands in subalpine of the middle of Yunnan Province were studied using standard plot sampling combined with biomass measurements.The results showed that the carbon contents of different organs in HSS,YNS,DYS,GSL,CL were(471.49 37.01)~(512.326.45)g/kg,(465.137.44)~(499.8017.58)g/kg,(480.1215.67)~(540.09 33.19)g/kg,(456.1366.35)~(516.0241.53)g/kg,and 504.2859.65~576.1037.33g/kg, respectively;the carbon content of CL was 1.07~1.14times higher than the other forests.Biomass of HSS and CL was higher than the average biomass of five forest types[(191.26412.92)t/hm~2],the biomass of YNS,DYS and GSL was 203.06%,1 928.25%and 1 744.40%lower than the average;the average biomass of different organs in five forest types decreased in the order:trunk>branch>root>leaf>bark,the average biomass of trunks was 6.40,2.38,8.18and 3.53times of branch,root,leaf and bark,respectively;carbon storage of different organs in 5forest types was proportional to biomass,which decreased in the order:HSS >CL>YNS>DYS>GSL.In conclusion,carbon storage of HSS,YNS and CL was higher,which had a great contribution to vegetation carbon in Yunnan Province.Carbon sequestration abilities of HSS,YNS and CL were stronger than the others.We should increase protection and improve forest quality by increasing forest quality and carbon density,formulate feasible forest management measures,and make them play better roles in carbon sinks in response to climate change.
