Reconstruction of paleohydrological regime, vegetation change, and peat accumulation in a bog in the Kas-Sym interfluve
- 36 Downloads
Comprehensive stratigraphic analyses of a standard peat profile laid on a large oligotrophic bog in the interfluve of Kas and Sym rivers, left tributaries of the Yenisei River, allowed reconstruction of local vegetation change and hydrological regime over a period of seven thousand years. The established three stages in vegetation succession in a local bog correspond to different degree of humidification. The development of bog ecosystem is found to be scarcely affected by regional climate. The process and rate of peat accumulation varied in different periods of the Holocene. The average rate of peat accumulation in the profile was 0.88 mm/year.
