Аннотация: Calculating the carbon balance of forests is necessary for correct estimation of their ecological functions as well as for the fulfillment of the obligations of the Russian Federation under the United Nations Framework Convention on Climate Change (UNFCCC). The computer program "Regional Assessment of Forest Carbon Budget" (ROBUL) developed by the Center for Ecology and Productivity of Forests of the Russian Academy of Sciences is used for calculations of the carbon balance of forests in the national greenhouse gas inventories. The objective of the proposed article is to evaluate the correctness of the assumptions and algorithms adopted in ROBUL and to propose some improvements to refine the estimation of the carbon balance of forests: – the use of a smooth curve of tree growth; – accounting for the contribution of over-mature forests; – the use of refined values of conversion coefficients [growing stock - carbon]. The paper also discusses the quality of State Forest Register data that are used in calculations. Assessments of the carbon balance of forests have been carried out using the original version of the ROBUL and its modification. The comparison has not revealed significant differences of estimates of the carbon uptake. Regional values of forest carbon balance per unit area are comparable with estimates of this indicator for countries with similar climatic conditions. The proposed improvements to the ROBUL make it possible to clarify the assessment of the carbon balance of Russian forests.
