Abstract

Current state of forest carbon budget accounting both in Russia and abroad is characterized by wide variety of methodological approaches and models. Therefore, final estimates have discrepancies. The results of comparative analysis of methods used to assess carbon sequestration in pine-birch forest stands are presented. The composition, growth and biological productivity of forest stands were analyzed as well as carbon stock was calculated for pine-birch forest stands in various age groups in the Central Forest-Steppe. The dynamics of biological productivity of modal forest stands with mixed composition is investigated. Significant differences were found in quantitative assessment of carbon deposited by forest stands obtained with three different methodologies. Discrepancies in carbon content estimations in forest stands with different age and composition obtained by different methods vary from 2.0 to 33.9%. The problem of reliable assessment of carbon sequestration by forest ecosystems of the Central Forest-Steppe requires regional approaches in development of assessment methods to provide precise results and minimize uncertainty of evaluations

沃罗涅日地区松桦林人工林固碳核算方法的比较评价

目前俄罗斯和国外的森林碳预算核算的特点是方法方法和模型种类繁多。因此，最终的估计存在差异。本文介绍了松桦林林分碳汇评价方法的比较分析结果。分析了中部森林草原不同年龄段松桦林林分的组成、生长和生物生产力，并计算了碳储量。研究了混合组成模式林分生物生产力的动态变化。3种方法对林分碳储量的定量评价结果存在显著差异。不同方法得到的不同林龄和组成林分碳含量估计值差异在2.0 ~ 33.9%之间。对中央森林草原森林生态系统的固碳能力进行可靠评估的问题要求在制定评估方法时采取区域办法，以提供精确的结果并尽量减少评估的不确定性
