摘要
通过标准地调查和生物量实测相结合的方法,对滇中亚高山5种典型森林——华山松(HSS)、云南松(YNS)、滇油杉(DYS)、高山栎(GSL)和常绿阔叶林(CL)乔木层植物各器官碳含量、生物量、碳储量及分配特征进行了比较研究。结果表明:HSS,YNS,DYS,GSL,CL各器官碳含量变幅分别为(471.49±37.01)～(512.32±6.45)g/kg,(465.13±7.44)～(499.80±17.58)g/kg,(480.12±15.67)～(540.09±33.19)g/kg,(456.13±66.35)～(516.02±41.53)g/kg和(504.28±59.65)～(576.10±37.33)g/kg。CL各器官的碳含量均值为其他各森林类型的1.07～1.14倍。HSS和CL生物量高于5种典型森林类型的生物量均值[(191.264±12.92)t/hm2],YNS,DYS和GSL生物量低于生物量均值的203.06%,1 928.25%和1 744.40%。不同森林类型各器官生物量均值总体上表现为干>枝>根>叶>皮,树干生物量均值分别为枝、根、叶和皮的6.40,2.38,8.18,3.53倍。不同森林类型各器官碳储量与生物量呈正比例关系,碳储量大小表现为HSS>CL>YNS>DYS>GSL。综上,华山松、云南松和常绿阔叶林乔木层植物碳储量较高,固碳能力较强,应加大保护力度,提高林分质量增加林分碳密度,制定出切实可行的森林管理措施,更好地发挥其在应对气候变化中的碳汇功能。
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)～(512.32±6.45)g/kg,(465.13±7.44)～(499.80±17.58)g/kg,(480.12±15.67)～(540.09±33.19)g/kg,(456.13±66.35)～(516.02±41.53)g/kg,and 504.28±59.65～576.10±37.33 g/kg,respectively;the carbon content of CL was 1.07～1.14 times higher than the other forests.Biomass of HSS and CL was higher than the average biomass of five forest types[(191.264±12.92)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 6.40,2.38,8.18 and 3.53 times of branch,root,leaf and bark,respectively;carbon storage of different organs in 5 forest 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.
