| 摘 要： | ~(14)C测年已为海洋研究工作广泛应用,但由于时有不合理取样或在运用数据时没有充分考虑各种海洋环境和动力因素,因而产生无法使用数据作合理解释的现象。本文试从海洋样品本身和海洋各种营力作用分析各种数据差异的来源,认为海洋环境特别是海岸带环境的复杂性是造成海洋样品~(14)C测年数据差异的主要原因,它可能影响样品的代表性或使数据解释时得出错误结论.并指出在运用年代结果时一定要充分考虑地质地理和各种营力作用因素。

| Abstract: | The carbon-14 dating data collected from the coastal and continental shelf region of our country already numbers several thousands, playing an important role in oceanographic research. But due to irrational sampling and not fully taking various environmental and dynamical factors in consideration during data application, error is produced or the phenomena that data can not be used in rational interpretation arises. The article analyses the cause of error. These are caused by the sample itself and the difference of initial carbon-14 concentration, as well as a variety of force factors including the destruction, decomposition, exchange, erosion, mixing and transportation effects. Among all these factors, complexity of the marine environment, especially the complexity of the coastal region, is the principal reason for causing data error in carbon-14 dating. |
