Growth of the dominant woody plants of floodplain communities in the changing hydrological and climatic conditions.

摘要

Poplars and willows growing in fragments of Vah river floodplain communities were analysed on two stands with different dynamics of the hydrologic regime. There was confirmed statistically significant influence of several hydrologic and climatic characteristics on radial increment of poplars and willows. On both analysed stands, decrease of radial increment of willows was found out from the beginning of eighties, which is statistically significant in some years. Evident decrease of radial increment of poplars on locality Dulov Dvor began only after year 2000. On locality Calovec, this woody plant showed more or less positive increment response. According to the obtained data, poplar appears to be more adaptable woody plant under conditions of long-term trend of groundwater level decrease.
