| 摘 要： | 北京周口店第一地点和南京直立人地点是我国重要的古人类化石地点。近年来,采用TIMS铀系测年等手段对这两个地点的年代重新进行了测定,将北京和南京直立人生存年代均前移了100ka以上。南京直立人的时代可能大于500ka,抑或580ka。北京直立人的时代介于距今400ka至650ka,抑或800ka。新的年代框架促进了两个地点地层与环境的研究。重点梳理两个地点的年代学、地层学等方面的研究进展与分歧,并对测年方法与结果、古生物与地层分析等方面的不确定性或多解性进行了讨论。尽管这两个地点在时代和环境研究方面仍存疑问,有些问题一时尚难澄清,但还是尝试提出了解决这些问题的部分途径和方法。

| Abstract: | The site of Nanjing Homo erectus and the Locality 1 at Zhoukoudian, Beijing are the important palaeoanthropological sites in China. In recent years, the ages of these two sites have been newly measured by thermal ionization mass spectrometric (TIMS) U-series dating. Their ages were both antedated by over 100ka. The age of Nanjing Homo erectus is possibly >500ka or 580ka and that of Peking Man ranges about 400ka to 650ka or possibly 800ka. The new age frame promotes the researches on the strata and the environments in these two sites. The paper emphasizes the recent progress and difference on the research of chronology and stratigraphy in these two sites, and discusses the uncertainty or multi-results of dating methods and results, along with paleontology and stratigraphic analysis. Although there are some doubts about the study on age and stratum in these two sites, some of which are still difficult to explain clearer in the short term. This paper attempts to put forward some approaches and methods to solve those problems. For example, the research on paleomagnetic stratigraphy of Locality 1 at Zhoukoudian can verify the age by TIMS dating and provide the chronological table of stratigraphic sequence in the lower part of this site. Similarly, the research on the fossil teeth of Nanjing Homo erectus by nondestructive U-series dating also can distinguish and verify the stratum and the age of Homo erectus in these sites. |
