| Abstract: | Two years' pollen influx and pollen vertical distribution in the coniferous and deciduous broad-leaved mixed forest of Changbai Mountains in 2008 and 2009 show that the pollen assemblages are dominated by arboreal pollen taxa in all samples,which are consistent with the vegetation composition.The pollen influx in 2009 is lower than that in 2008,the reason is concerned with more precipitation,lower temperature and wind velocity of florescence period.The pollen influx at different heights has similar dispersal trend in two years,showing that the pollen influx tends to increase between 0 and 22m,the maximum values appear at the height of 16m or 22m,however,the pollen influx declines gradually beyond the height of 22m.The results of 2008 and 2009 were similar to that of 2005 and 2006,indicating that the pollen assemblages are consistent at different heights,the vertical pollen influx has similar dispersal trend too. |
| Keywords: | Changbai Mountains pollen influx pollen assemblages coniferous and deciduous broad-leaved mixed forest pollen dispersion inter-annual comparison |
