Last 12,000 years vegetation history in and around the Furano Basin, central Hokkaido, Japan

富良野盆地東部の東鳥沼と山地の東大演習林上湿原について,年代測定と花粉分析学的研究を行なった。盆地における森林の主構成種は,Abies,Picea,Betula,Juglans(9~8 ky BP)~Quercus,Abies(8~5 ky BP)~Quercus,Alnus(5~4 ky BP)~Quercus,Abies,Picea(4 ky BP~現在)と変遷した。Quercusは温暖気候のもと8~4 ky BPで最も優勢であった。4 ky BPにAbies,Piceaが増加して現在に至る汎針広混交林が成立した。湿原は~9 ky BPから成立した。山地では,Picea,Larix,Pin...
