The zonation of peatland complex types and prevalence of peatlands are examined in relation to climatic and hydrological zones in northern Eurasia, particularly in Finland. Mutual coincidences were found in most cases and are considered causal. Climatic and hydrological factor gradients were in many cases steeper about the boundaries than within zones.
Keywords: peatland complex types, climatic and hydrological zones, zonation.

The small-scale production of sod peat in Finland is, generally, production on farms for their own use. According to two postal questionnaires made by the Forestry Department of the Work Efficiency Association there were, in Finland, in 1980 77 and in 1984 136 small producers of sod peat. In the questionnaires, the production technology, economy, availability, conditions, areas and quantities of small-scale producers were identified. According to the questionnaires peat production on farms is mainly practised by using the farm's own labour and on their own or a hired production area. The larger part of small-scale production of peat is production of sod peat. Other peat products produced on farms are milled peat, agricultural peat and horticultural peat.
Keywords: peat, production, technology.

Peatlands complexes, site type classification and utilization of peatlands in northeast China are reviewed. The number of mire plant species common to both Finland and northeast China is about 120. Peatlands have been reclaimed for agriculture for a long time, but amelioration for forestry is only in the beginning. However, the potential of peatlands for forestry after drainage is considered high.
Keywords: China, peatland complexes, peatland site types, peatland utilization.
