Outline of Final Research Achievements

Field observation in Mongolian forest-steppe transition zone and analysis of its soil organic components were conducted to obtain feasible quantitative parameters for vegetation transition model. We clarified following quantitative features for the interactions between the two vegetation types and between vegetation development and soil formation: 1) Forest vegetation has been present there at least for 150 years while the soil organic matters aged 600-800 years in grass-covered area and about 6500 years in forest stand, which could provide quantitative parameters for time-scale of the vegetation transition; 2) Soil organic matters sampled from either vegetation types not always exhibit clear identity of the current vegetation type, from which we could expect that several vegetation transitions might have been occurred in the thousands years' past possibly induced by human activity or forest fire.
