新仙女木时期的寒潮逆转对日本群岛晚冰期狩猎采集者生存的影响，通过对从晚冰期和全新世初出土的88个地点（33214C）获得的14c数据进行综合汇编。根据日本列岛及其周围不同沉积物中的黄土堆积和花粉记录估算的东亚季风强度和植被历史表明，在新仙女木期开始时，气候突然转变为凉爽和干燥，加上格陵兰岛记录的Dansgaard-Oeschger旋回。14c年代学分析表明，从Bølling-Allerød到新仙女木期，站点数量减少，从新仙女木期到前寒武纪，站点数量增加。然而，从站点分布分析推断的人类种群动态与之前的b ølling - allero ød和之后的Preboreal相比变化不大。此外，在新仙女木时期开始之前，狩猎采集者就一直使用陶瓷技术，而在新仙女木时期被破坏的陶瓷容器的数量在全新世开始时急剧增加，这意味着在新仙女木时期结束后，狩猎采集者的社会经济发生了实质性变化。
The effect of the Younger Dryas cold reversal on the survival of Late Glacial hunter-gatherers in the Japanese Archipelago is evaluated, through a synthetic compilation of14C dates obtained from excavated Late Glacial and initial Holocene sites (33214C dates from 88 sites). The estimated East Asian monsoon intensity and vegetation history based on the loess accumulations in varved sediments and pollen records in and around the Japanese Archipelago suggest an abrupt change to cool and dry climate at the onset of Younger Dryas, coupled with the Dansgaard–Oeschger Cycles as recorded in Greenland. The chronometric placement of sites based on an assessment of14C dates show that the site numbers decrease from the Bølling–Allerød to Younger Dryas and increase from the Younger Dryas to Preboreal. However, human population dynamics inferred from a site distribution analysis was little changed from the previous Bølling–Allerød and to the following Preboreal. Moreover, hunter-gatherers consistently employed ceramic pottery technology since its emergence prior to the onset of Younger Dryas, while the quantity of ceramic vessels that were undermined during the Younger Dryas dramatically increased at the onset of the Holocene, implying that a substantial change in hunter-gatherer socioeconomy occurred after the end of Younger Dryas.
