| 摘 要： | 分析总结了中国陆架210Pb测年现状及取得的成果,评价了210Pb测定沉积速率的可靠性。由于数据处理及成果表达的不统一,得到的沉积速率只能定性—半定量地表征沉积作用强度。根据210Pb测年现状、陆架沉积环境特征探讨了改善210Pb应用的有关问题,认为合理的选区、必要的校正、统一的成果表达是提高210Pb应用水平的重要因素。

| Abstract: | The achievements and current situation of 210 Pb dating in the continental shelf of China were summarized. The reliability of 210 Pb dating for the sedimentary rate was commented. It is shown that the sedimentary rate calculated from 210 Pb dating only qualitatively or semi quantitatively responds to the real sedimentation strength, due to the ununity of data process and result expression. Based on the current situation of 210 Pb dating, the characters of the sedimentary environment in the shelf, the problems how to improve the reliability of 210 Pb dating for sedimentary rate are discussed and analyzed, indicating that the reasonabale selection of study area, necessary adjustment and unity of result expression are the important factors to improve the application of 210 Pb dating in the continental shelf of China. |
