Abstract . An approach to the implementation of spatial inventory of greenhouse gas sinks and emissions in forestry sector is presented. The algorithms for disaggregation of official statistical data on forests at the regional level, and formation of geodistributed database using the digital map of land use are proposed. As an example the forests of Subcarpathian Voivodeship of Poland were investigated. This study presents the results of modeling the flow of carbon in forest phytomass taking into account different tree species composition, age class and other characteristics. The ‘regional’ coefficients for phytomass and carbon deposited were clarified taking into account regional specificity. Also an algorithm for determining aboveground and underground phytomass of tree by its stock and forests of different types has been created. The correlation between the total area and stock for each species of forest-forming stands was analysed. The multilayer digital maps of deposited carbon, and greenhouse gas emissions in forests of Subcarpathian Voivodeship were created. For the spatial inventory of forest phytomass the territory of voivodeship was divided into square areas 2×2 kilometers in size, and stock phytomass in each such elementary area has been analised. Acheaved results were verified using GIS technology, and forest inventory data.

Key words : information technology, digital maps, GIS, IPCC methodology, forest inventory, deposited carbon.
