植物化石からみた日本の第四紀

抄録

A floral change in Japan during the Quaternary period based on both macroscopic and microscopic fossils is given. Much attention is paid to the past distribution of the same or closely related plant species found in temperate mixed coniferous and deciduous broad-leaved forests between continental eastern Asia and Japan. An attempt is made to illustrate the relative importance of the constituents by sectorial division of the circle for two periods having a defined span of time: one covers the lowermost or the lower part of the Shimosueyoshi period and the other corresponds to the ages of the Aira-Tn (AT) ash during the Tachikawa period.
