After a broad survey of the vertical zone in Beitai, Xiaowutaishan mountain, a surface pollen spectrum is established. The climatical significance of some important species, such as Picea meyeri, Larix principis-ruprechtii and Betula is also analysed. This research demonstrated: Surface pollen content of Betula and Pinus is much more than their coverage in community, so they have extra-representation; Surface Pollen content of Picea is corresponded with its coverage in community; Because Larix has low pollen productivity and bad preservation ability of pollen, it has low representation for its coverage in community. As for their climatical significance, Picea meyeri indicates cool-wet habitat; Larix principis-ruprechtii indicates cool-dry climate; Betula has a broad ecological amplification, Betula albo-sinensis has a natural inclination for cool climate, Betula platyphylla has a natural inclination for dry climate.
