摘要

Geological Survey of Finland has investigated 1.7 million ha of the 5.1 million ha area covered by geological peatland in Finland. The study material contains about one million study points and 12 000 single peatland basins, from where the peat geological data has been collected. Based on these data, the present study assesses the peat resources of Finland and their exploitability. Peatlands, which are technically suitable for the peat industry, cover a total area of 1.2 million ha and contain 29.6 billion m~3 of peat in situ.. Calculations of economical and environmental facts that will limit the use of mires have not been taken into account. Slightly humifed peat suitable for horticultural and environmental use totals 5.9 billion m~3 in situ and energy peat totals 23.7 billion m~3 in situ with an energy content of 12 800 TWh. The effective energy density of the areas appropriate for energy production is 0.54 MWh/ m~3 in situ. Sphagnum peat account for 54 % and Carex peat for 45 % of recoverable peat reserves. The remainder, 1%, is composed of Bryales peat, the bulk of which are encountered in the North-Finland area. The highest values of humification degree are located in Finnish Lake area, in Central Finland. The average ash content is 3.4% of dry mass, sulphur content 0.20% of dry mass and dry bulk density 87 kg/m3 in situ. The mean depth of the geological peatland is 1.41 m. In the area exceeding 1.5 m in depth the peat layer is 2.50 m thick on an average. Thirty-seven per cent of the mires, covering a total area of 1.9 million ha, are over 1.5m deep. Total Finnish national peat reserves are account for 69.3 billion m~3 in situ. Dry solids total 6.3 billion t. The carbon storage of Finnish mires is 3.2 billion t.
