摘  要：
文章以赤峰市落叶松人工林为研究对象,分析了不同林龄各器官的生物量、碳含量和碳储量。结果表明:(1)落叶松人工林不同林龄各主要器官平均生物量均表现为成熟林>近熟林>中龄林>幼龄林,其中以干器官变化幅度最大。各器官中,以树干生物量所占比重最大,其次为根、枝、叶。影响生物量的主要因素是林龄,次要因素是不同器官。(2)落叶松不同林龄各器官碳含量在470~505 g/kg之间,差别不大,其平均碳含量为481.07 g/kg。此数值可为落叶松碳储量相关研究提供数据支持。(3)落叶松各器官平均碳储量随着林龄增加均呈逐渐增高趋势;相同林龄各器官平均碳储量大小为干>根>枝>叶。(4)落叶松人工林各林龄乔木层碳密度随林龄增加呈现先升高趋势,其变化呈乘幂关系。截止2013年末,赤峰市落叶松人工林乔木层总碳储量为3.8×106t。

摘  要：
The biomass, carbon content and carbon storage of organs at different stand ages in Chifeng larch plantation were analyzed.The results showed that:(1)The average biomass of the main organs in different ages of Larch plantation showed as follows: mature forest>near mature forest>half-mature forest>young forest. Among them, the trunk organ changed most. Among all the organs, trunk biomass accounted for the largest proportion, followed by roots, branches and leaves.The main factor affecting biomass is stand age, and secondary factors are different organs.(2)The carbon content of different organs of larix gmelini at different ages is 470~505 g/kg. The difference is not big, and the average carbon content is 481.07 g/kg. These values can provide data support for the study of larch carbon storage.(3) The average carbon storage of each organ gradually increased with the increase of stand age.The average carbon storage of all organs at the same age was stem>root>branch>leaf.(4)The carbon density of tree layer of larch plantation increased with the increase of forest age, and its change was a power relation. By the end of 2013, the total carbon reserves of the larch forest trees in Chifeng City were 3.8×106 t.
