研究了日本中部冈山遗址沉积于6.300-3.000 yBP的化石木材组合。第三层含化石木，按层间火山灰划分为3个亚组，共研究化石木3618株。在组成上，落叶阔叶树占主导地位，并伴有一些万年青针叶树。在直径分布中，9个类群占直径超过10 cm的个体的近90%。9个主要类群和3个次要类群的空间分布以及粗度个体的空间分布表明：1）5000 - 4500 yBP，白蜡属植物建立了一个低地森林，并伴随着赤杨组、槭属和七叶树（Aesculus turbinata）; 6，300 - 3，000 yBP，栎组（Quercussect. Prinus）和栗树组（Castaneacrenata）构成了陡坡林，5，000 - 4，500 yBP，鹅耳枥组（Carpinussect. Eucarpinus）成为陡坡林的主要组成部分，4，500 - 3，000 yBP，日本奥斯特里娅（Ostryajaponica）取代了栗树组。与其他五个同时代的化石木材组合的比较表明，流行ofFraxinus占主导地位的森林在绳文时代晚期至最后在关东平原南部的一部分。
Fossil wood assemblages deposited during 6.300–3.000 yBP, are studied at the Akayama Site, central Japan. Layer III containing fossil woods was divided into three subunits according to intercalating tephras, and total 3618 fossil woods were studied. In the composition, deciduous broad-leaved trees dominated, accompanied by some evergreen conifers. In the diameter distribution, nine taxa accounted for nearly 90% of individuals exceeding 10 cm in diameter. Spatial distribution of nine major and three minor taxa and that of thick individuals clarified the following points: 1)Fraxinusestablished a lowland forest during 5,000–4,500 yBP, accompanied byAlnussect.Gymnothyrsus, Acer andAesculus turbinata; 2) small trees ofAlnussect.Gymnothyrsusextensively intermingled in the lowlandFraxinusforest during 4,500–3,000 yBP; 3)Quercussect.Prinusand Castanea crenata constituted escarpment forests during 6,300–3,000 yBP; 4)Carpinussect.Eucarpinusbecame a major component during 5,000–4,500 yBP, andOstrya japonicareplacedCastanea crenataduring 4,500–3,000 yBP. Comparison with the other five contemporaneous fossil wood assemblages shows prevalence ofFraxinus-dominant forests during the Late to Latest Jomon Periods in the southern part of the Kanto Plain.
