摘要:

In two small mountain basins of the Ligurian Apennines the relationships between recent pollen spectra and vegetation were studied. Local pollen dispersal was emphasized by comparing each surface sample with the corresponding vegetation. The extralocal and regional pollen rain was observed in surface samples of the peat bogs in the small basins through the relationships between these spectra and the composition of the vegetation of the catchment basins. For the quantitative valuation of the latter, vegetation maps and a more local system of direct counting were employed. In this way quantitative information about pollen representation (R/P) of many arboreal, shrubby and herbaceous plants was obtained; however, for the moment the value of the results should be considered local while awaiting wider comparisons.
