嵩山南坡不同林龄栓皮栎人工林碳密度分布特征
Carbon density distribution characteristics of Quercus variabilis plantations with different stand ages on the southern slope of Songshan Mountain
摘要
Abstract
[Objective]This study aims to investigate the carbon density distribution characteristics of the vegetation layer and surface soil in Quercus variabilis plantations at different stand ages,providing a scientific basis for rational forest management strategies.[Method]Three stand age stages-including young,middle-aged,and near-mature Quercus variabilis plantations-on the southern slope of Songshan Mountain were selected as study objects.Field plot surveys,sample collection,and laboratory analy-ses were conducted.At the individual tree level,biomass,carbon mass fraction,and carbon storage allocation characteristics of different components were analyzed.At the stand level,the carbon density distribution of the tree layer,shrub-herb layer,litter layer,and surface soil were examined across dif-ferent stand ages.[Result]1)Significant differences were observed in the biomass and carbon storage of different components of Quercus variabilis trees at different stand ages.The carbon mass fraction in the bark and stem was significantly higher than that in the roots,branches,and leaves(P<0.05),indicating a strong carbon storage capacity.2)The carbon densities of the tree layer in young,middle-aged,and near-mature stands were 41.390 t·hm-2,67.943 t·hm-2,and 93.085 t·hm-2,respectively.The carbon density of the shrub and herb layer in these stands was 2.718 t·hm-2,1.618 t·hm-2,and 1.098 t·hm-2,respectively,with significantly higher values in young stands than in middle-aged and near-mature stands.However,there were no significant differences in carbon density of the litter layer and surface soil layer aross the three stand ages 3)The total carbon density of the young,middle-aged,and near-mature Quercus variabilis plantations was 66.164 t·hm-2,95.473 t·hm-2,and 120.476 t·hm-2,respectively.Across all stand ages,the carbon storage in the tree and soil layers accounted for over 96%of the total stand carbon storage.[Conclusion]In the Quercus variabilis plantations on the southern slope of Songshan mountain,carbon density exhibits distinct variations among the different components within individual trees,as well as across the tree layer,shrub-herb layer,litter layer,and soil layer.Overall,the carbon density shows an increasing trend with stand age.关键词
