Abstract
Results of the organic carbon stock assessment in pools of forest soils and forest litter on the forest monitoring plots in different natural zones of Ukraine are presented. Organic carbon in forest ecosystems is concentrated in phytomass, litter and deadwood, and in soil humus. During the study the amount of forest litter stock, soil density and carbon content in soils (in 30-sm depth) and in litter were determined. For plain forests the average carbon stock in litter is 8±1 tonnes of C/ha, this index for coniferous is 13,1±2 tonnes C/ha, and for deciduous – 4±0,4 tonnes C/ha. Average carbon content in forest litter under our research (38 %) is close to the coefficient, recommended by IPCC (37 %). Maximum carbon stock in soils of plain forests is observed in Forest-steppe zone (75 tonnes C/ha); in soils of Forest zone carbon stock is 49 tonnes С/ha and in Steppe zone – 43 tonnes C/ha. In Oak forests this index is 88 tonnes C/ha, and in pine forests– 41 tonnes C/ha. Average stock in forest soils pull in forests of the plain part of Ukraine is 67,3 tonnes C/ha, and in mountain forests – 96,6 tonnes C/ha. Obtained results are preliminary. It is necessary to continue the research for more detailed and precise assessment, with covering the variety of forest types and spatial and time dynamics of carbon stock in forest pools.

Accumulation of 137Cs in forest ecosystems of Volyn Polissya in the western traces of Chornobyl accident
The studies have proved that the main mass of 137Сs of forest soils is located in the forest bedding in the top humus layers. The distribution of radionuclide in depth increases from the sod-podzolic to the sand and dry...
Resin productivity of scots pine at different type of spatial distribution of trees in Small Polissya
The paper presents the results of investigation of the spatial structure of tapped Scots pine. Peculiarities of distribution of the trees of different resin productivity categories are revealed. Resin productivity depend...
Forecasting of fire danger by weather conditions in forests of the green belt of Kharkiv city
The methods of predicting forest fire occurrence based on the forecast by meteorological indicators are quite efficient and less costly. However, due to the nature of some forest areas, it is not always possible to preci...
