研究了亚洲边缘季风区中全新世至晚全新世过渡期亚洲夏季风(ASM)变化的时间序列。我们使用了绝对年代为230年的记录，只有20年的测年误差，以及来自黄土高原西部万象洞的石笋WXB07-4顶部22 mm段的氧同位素数据，其时间分辨率平均为8年。ASM强度从6420~4920aBP逐渐减弱，主要表现为三个阶段：(1)6420~6170aBP降水量较大的加强期，(2)6170~5700aBP的平稳波动区间，(3)5700~4920aBP的突发性极端弱化期。有趣的是，ASM的极端减弱间隔发生在5700-4920 a BP之间，这种突变发生在5430 a BP，被称为5400 a BP或5.4 ka BP。这一时期包括290年的逐渐减弱和350年的缓慢加强。这与亚洲季风区的一些洞穴记录在测年误差内是同步的。与中国7000年来的考古档案相比，黄河流域仰绍文化和西辽河流域红山文化的早期衰落发生在ASM降水逐渐减少的时期。降水的急剧减少可能与渭河流域阳关寨遗址庙底沟文化、豫西黄河流域阳哨文化中段、黄河下游大汶口早期文化、辽河流域西部红山中段红山文化的衰落有关。在5400 a BP事件(5430-4920 a BP)的后期，幅度的小幅增加和随之而来的ASM降水的急剧减少也可能与同期仰韶晚期和红山文化的繁荣和消失、以渭河关中盆地阳关寨遗址为代表的仰绍晚期文化的消失、上游大地湾遗址的第四期仰绍文化、大汶口文化中期的开始及其晚期的形成和龙山文化的崛起，以及长江下游曲家岭和良渚文化的崛起有关。与青藏高原石笋降水记录相比，黄河上游马家窑文化在5300aBP的上升和扩张可能与5400a BP事件后期夏季风降水在较高海拔而不是较低高度的显著增加有关。
We explored a time series of the Asian summer monsoon (ASM) variability during the transition period from the middle to the late Holocene in the marginal Asian monsoon region. We used an absolutely dated 230Th record with only a ~20-year dating error, and oxygen isotope data with an 8-year average temporal resolution from the top 22-mm segment of stalagmite WXB07-4 from Wanxiang Cave, western Loess Plateau. The ASM intensity weakened gradually from 6420 to 4920 a BP, which was mainly characterized by three phases: (1) a strengthening phase with a higher precipitation amount between 6420 and 6170 a BP; (2) a smooth fluctuating interval during 6170–5700 a BP; and (3) a sudden extreme weakening period from 5700 to 4920 a BP. Interestingly, the extreme weakening interval of the ASM occurred during the period between 5700 and 4920 a BP, an abrupt change dated at 5430 a BP, which is known as the 5400 a BP, or 5.4 ka BP, event. The period included 290 years of gradual weakening, and 350 years of slow strengthening. This was synchronous with some cave records from the Asian monsoon region within dating errors. Comparing with Chinese archaeological archives over the past 7000 years, the early decline of the Yangshao Culture in the Yellow River Basin and the Hongshan Culture in the West Liao River Basin occurred during the period of gradual decrease of ASM precipitation. The dramatic decline in precipitation, caused by the extreme weakening of the ASM at 5400 a BP, may have been partly related to the decline of the Miaodigou Culture at the Yangguanzhai site in the Weihe River valley; the middle Yangshao Culture in western Henan in the Yellow River Basin; the early Dawenkou Culture on the lower reaches of the Yellow River; and the middle Hongshan Culture in the west of the Liaohe River valley. During the later period of the 5400 a BP event (5430–4920 a BP), a small amplitude increase and a subsequent sharp decrease of ASM precipitation may have also been linked to the contemporaneous prosperity and disappearance of the late Yangshao and Hongshan cultures; the disappearance of the late Yangshao Culture represented by the Yangguanzhai site in the Guanzhong basin on the Weihe River; the fourth phase of the late Yangshao Culture on the upstream Dadiwan site; the beginning of the middle Dawenkou Culture, the formation of its late stage, and the rise of the Longshan culture; and the rise of the Qujialing and Liangzhu cultures on the lower Yangtze River. Compared with the stalagmite precipitation records on the Qinghai-Tibetan Plateau, the rise and expansion of the Majiayao Culture in the upper Yellow River valley at 5300 a BP may have also been connected to the more dramatic increase of the summer monsoon precipitation at higher, rather than lower, altitudes during the late 5400 a BP event .
