Development of the villages and the use of forest resouces during the Jomon Era. Archaeological, dendrochronological and folkloric analyses.

用树木年轮宽度和树木年轮氧同位素分析的技术对青田绳纹遗址的木桩进行分析，揭示了大约公元前477年和公元前530年两个主要的村庄建设时期，这是日本第一次成功地精确确定绳纹时代人类学事件的年代。对Aota遗址及其周围沉积物的花粉分析表明，该村附近保留着绳纹最重要的木材和食物资源植物栗树。

Dendrochronological techniques of both tree-ring width and tree-ring oxygen isotopic analyses applied to the wooden posts of Aota Jomon Site revealed that there were two major village construction periods of ca. BC477 and BC530, the first success in Japan to precisely date anthropological events in Jomon Era. Pollen analysis of deposits in and around Aota Site showed chestnut trees, the most important wood and food resource plant in Jomon, were maintained nearby the village.
