東北地方における亜高山帯の植生史について : II.八幡平

抄録

Pollen analytical studies were made on materials collected from thirteen moors developed on the Hachimantai Mountains in order to clarify the vegetational history in the subalpine zone of the mountain range. The Abies mariesii forest began increasing in the subalpine zone 3000-2500 years ago, and it markedly extended there during the last 1500 years. Before then, it was suggested that the region was covered by a deciduous scrub dominated by Quercus from 5000 to 3000-2500 years ago.
