摘要： 对黑龙江省同江县96—QP剖面从下至上划分4个孢粉组合带:1是以蒙古栎-桦属-蒿属-苔草属-禾本科-水龙骨科为主组合带;2是以蒿属-莎草科-禾本科-桦属-栎属为主组合带;3是以桦属-蒙古栎松属-蒿属-莎草科-禾本科为主组合带;4是以松属-桦属-蒙古栎-蒿属-苔草属为主组合带。这4个孢粉组合带清楚地反映了古植被、古气候演替4个阶段:依次为温性落叶阔叶林→针、阔叶混交林-草原→以落叶阔叶树稍多的针、阔叶混交林-草原→以松占优势的针、阔叶混交林。其气候变化是温暖湿润-温和略干-温和略湿-温凉湿润。

Abstract: Based on the sporo-pollen analysis and the 14C dating from the Tongjiang region of 96-QP core, the four sporo-pollen assemblages have been distinguished in ascendant order:Zone 1:Quercus mongolica—Betula—Artemisia—Carex—Gramineae—Polypodiaceae Zone.Zone 2:Artemisia—Cyperaceae—Gramineae—Betula—Quercus Zone.Zone 3:Betula—Quercus mongolica—Pinus—Artemisia—Cyperaceae—Gramineae Zone.Zone 4:Pinus—Betula—Quercus mongolica—Artemisia—Carex Zone.Sporo-pollen zones mentioned above can clearly represent 4 evolutional stages of vegetation and climate. In ascendant order these stages are:the temperate deciduous broad-leaved forest→conifer and deciduous broad-leaved mixed forest-grass→deciduous broad-leaved forest containing coniferous tree-grass→conifer as deciduous broad-leaved mixed forest dominated by Pinus. The climatic variations are:warm and moist-temperate and little dry-temperate and little moist-cool and moist.
