Abstract:
A comparison of pollen assemblages and pollen influx between 2005 and 2006 in mixed conifer and broad-leaved forest of Changbai Mountains shows that the pollen assemblages are similar with arboreal pollen taxa dominated in all the samples,but the percentages of arboreal pollen are slightly higher and shrub and herb pollen are lower in 2006 than in 2005. The reason is concerned with more precipitation in florescence and lower temperature in 2005. But both in 2005 and 2006,the vertical pollen influxes show si...
