摘　　要：基于曲靖市海寨林场2016年度森林资源二类调查资料数据,利用生物量扩展因子法,结合各主要乔木树种的计算参数,分析研究了海寨林场主要乔木树种于不同年龄组和不同林分起源类型的碳储量及碳密度分布特征。结果表明,海寨林场主要乔木树种总面积为14998.3 hm^(2),总蓄积量为1482230 m^(3),总碳储量为630829.35 t,平均碳密度为42.06 t·hm^(-2),反映出海寨林场乔木林总体而言林分质量优良,固碳潜力较大。对于不同树种而言,碳储量大小依次为华山松、云南松、栎类、柏木、软阔、杉木、桤木、蓝桉、硬阔;对于不同林龄而言,碳储量和碳密度均随林龄增加呈现增长趋势;对于不同起源类型而言,人工林的面积、碳储量和碳密度大于天然林。因此,碳储量的高低受到树种类型、起源方式、林龄等多重因素的影响。为了更加有效地管理和保护森林碳循环,应当重视林分结构的合理配置并不断优化,从而促进森林生态系统的稳定性和可持续性,进而实现更好的碳储存和生态保护效果。Based on the data from the second-class forest resource survey of the Haizhai Forest Farm in Qujing City in 2016,using the biomass expansion factor method and the calculation parameters of the main tree species,this study analyzed the carbon storage and carbon density distribution characteristics of the main tree species in different age groups and different forest origin types in the Haizhai Forest Farm.The results showed that the total area of the main tree species in the Haizhai Forest Farm was 14998.3 hm^(2),with a total volume of 1482230 m^(3) and a total carbon storage of 630829.35 t.The average carbon density was 42.06 t·hm^(-2),reflecting the overall good quality of the tree stands in the Haizhai Forest Farm and a large potential for carbon sequestration.In terms of different tree species,the carbon storage was ranked as follows:Pinus armandii,Pinus yunnanensis,Quercus spp.,Cupressus spp.,broad-leaved deciduous trees,Cunninghamia lanceolata,Castanopsis hystrix,Eucalyptus globulus and broad-leaved evergreen trees.In terms of different forest ages,both carbon storage and carbon density showed an increasing trend with increasing forest age.In terms of different origin types,the area,carbon storage,and carbon density of artificial forests were greater than those of natural forests.Therefore,the carbon storage is influenced by multiple factors such as tree species,origin type,and forest age.In order to manage and protect forest carbon cycling more effectively,attention should be paid to the rational allocation and continuous optimization of forest stand structure,thereby promoting the stability and sustainability of forest ecosystems and achieving better carbon storage and ecological protection effects.
