In order to study pollen rain six funnel-like pollen traps were set up on tree trunks 1.3 m above the ground in a firspruce forest in. Changbai Mt. at 1,150 m a.s.1, for a time interval from June 1985 to August 1986. Pollen influx values were calculated by volumetricat and exotic pollen methods (see Table 1). Pollen representation of each major tree type, e. g. Pinus, Abies, Picea, Betula, Larix and some decideous broad-leaved trees, was deduced front a comparison between the percentage of the tree type in pollen spectrum and that in forest. The pollen spectrum obtained from pollen trap was compared with that extracted from surface; ample taken from the same vegetation zone; the differences and their possible causes are also discussed.
