中文摘要：

Jingshuiwan 旧石器时代的地点在长江的正确河岸上占据第二个平台。锂的集合被在卵石和大薄片上成为华南的典型锂的工业的砍 pers 和碎片 ers 描绘。这个地点的存款主要由河的沉积组成。从人工制品从被揭开的这些河的沉积提取的石英谷物用光学地刺激的 luminescence/single-aliquotregenerative-dose 技术被标明日期。标明日期的结果证明在这个地点的古老的人的活动发生在早上面的更新世(ca。70 ka ) 。Jingshuiwansite 的成功的年龄分析在三个峡区域并且甚至在华南在旧石器时代的开的地点的按年代先后的分析被看作主要突破。日期获得了帮助在这个区域建立旧石器时代的文化顺序的一个更完全的按年代先后的框架，并且在在中国学习现代人的起源忍受重要含意。

英文摘要：

The Jingshuiwan Paleolithic site occupies the second terrace on the right bank of the Yangtze River. The lithic assemblage is characterized by choppers and scrapers made on pebbles and large flakes the typical lithic industry of South China. Deposits of the site are mainly composed of fluvial sediments. Quartz grains extracted from these fluvial sediments from which the artifacts were uncovered were dated using the optically stimulated luminescence/single-aliquot regenerative-dose technique. The dating results show that ancient human activities at this site took place in the early Upper Pleistocene （ca. 70 ka）. The successful age analysis of the Jingshuiwan site is considered as a major breakthrough in chronological analysis of Paleolithic open site in the Three Gorges region and even in South China. The dates obtained help to establish a more complete chronological framework of the Paleolithic cultural sequence in the region, and bear significant implications in studying modern human origins in China.
