中文摘要	中亚干旱区是丝绸之路的核心区,也是史前人类扩散和东西方文化交流的重要通道.该区气候干旱,植被和生态群落受制于水文因素.由于缺乏精确年代控制的高分辨率古气候记录,中亚地区全新世水文变化及极端干旱事件在史前人口迁移和跨欧亚大陆文化交流中扮演的角色还不清楚.本文基于来自吉尔吉斯斯坦的石笋多指标记录,重建了中亚干旱区目前年代最精确(测年误差~6)、分辨率最高(~3年)、涵盖中晚全新世的降水变化序列.结果显示在5820~5180 a BP期间,该区存在一次持续时间为640年的超级干旱事件,主要受西风带北移的影响.这次干旱事件对中亚史前文化的发展产生了重要影响,很可能阻碍了史前东西方文化沿中亚绿洲路线上的相向扩散,使得最早的跨欧亚大陆文化交流在5000~4000 a BP沿着北方草原路线开展.随着大干旱后降水的逐渐增加和生态环境的恢复,中亚绿洲和河谷中增加的定居人口促进了不同绿洲之间的相互联系,进一步在4000~3000 a BP开辟了跨大陆文化交流的史前丝绸之路,为历史时期丝绸之路的最终开通奠定了基础.
英文摘要	Arid Central Asia(ACA), with its diverse landscapes of high mountains, oases, and deserts, hosted the central routes of the Silk Roads that linked trade centers from East Asia to the eastern Mediterranean.Ecological pockets and ecoclines in ACA are largely determined by local precipitation.However, little research has gone into the effects of hydroclimatic changes on trans-Eurasian cultural exchange.Here, we reconstruct precipitation changes in ACA, covering the mid-late Holocene with a U-Th dated, ~3 a resolution, multi-proxy time series of replicated stalagmites from the southeastern Fergana Valley, Kyrgyzstan.Our data reveal a 640-a megadrought between 5820 and 5180 a BP, which likely impacted cultural development in ACA and impeded the expansion of cultural traits along oasis routes.Instead, it may have diverted the earliest transcontinental exchange along the Eurasian steppe during the 5th millennium BP.With gradually increasing precipitation after the megadrought, settlement of peoples in the oases and river valleys may have facilitated the opening of the oasis routes, "prehistoric Silk Roads", of trans-Eurasian exchange.By the 4th millennium BP, this process may have reshaped cultures across the two continents, laying the foundation for the organized Silk Roads.
