摘　　要：为了明确不同森林经营模式对天然林碳储量的影响,推动经营区森林的保护、开发和持续利用,采用间接收获法获取样品,并运用低温外热重铬酸钾氧化-比色法测定植物碳含量,对9种经营模式下天然林碳储量进行比较分析。结果表明,选择采育结合的经营模式更有利于提高森林树干、树枝和根系的碳储量,但各种经营模式下的树叶碳储量差距不大。天然林分中碳储量的分布大致服从:乔木层>枯枝落叶层>草本层>灌木层,天然林的碳储量在采育结合的经营模式下最大,保植补育经营模式下最小,在定向培育和间伐调整的经营模式下处于中等水平。林分碳储量主要集中在乔木层,林分各层适宜的经营模式不同。从碳储量总量上看,天然林选择采育结合的经营模式更合理,更有利于提高森林资源的碳储量,促进其形成生态、经济效益俱佳的天然混交林推动森林生态系统的物质循环,推进生态系统的健康与可持续发展。In order to clarify the impact of different forest management modes on natural forest carbon storage,promote forests ’ protection,development and sustained utilization of business district,the author used indirectly harvesting method to obtain the sample,and the content of carbon in plants was determined with the method of potassium dichromate colorimetric,the natural forest carbon storage was carried on the comparative analysis under 9 kinds of management modes.The result showed that：the combination of cutting patterns were more conducive to improve the forest tree trunks,branches and roots of carbon storage,but the carbon storage of leaves had little difference under a variety of operating modes.The distributions of the carbon storage for the natural forest stands was generally subjected to the tree layer〉litter layer〉herb layer〉shrub layer,natural forest carbon storage was ready for the greatest in the combination of cutting patterns,and the conservation replanting mode was in the minimum,orientation training mode and thinning adjustment mode was in the medium.Forest carbon storage mainly concentrated in the tree layer,stands for each layer of the management mode were different,judging from the total amount of carbon storage,natural forest management mode selected combination of cutting patterns was more reasonable,more conducive to increase carbon storage of forest resource,promote to form the natural mixed forest which both were of high ecological and economic,push forward material cycle of forest ecosystem,promote the health of the ecological system and sustainable development.
