| 摘 要： | 运用137Cs法和210Pb法对核试验场区汇水区沉积物的沉积速率进行估算，对沉积物的蓄积峰进行年代判定。用分衰减段方法计算210Pb分布异常情况下沉积物的沉积速率，得到的沉积速率与137Cs法获得的沉积速率基本符合。结合应用137Cs法和210Pb法，可得到汇水区的沉积速率和沉积层的年代。

| Abstract: | ~(137)Cs method and ~(210)Pb method are applied to estimate the sedimentation rate in catchments of nuclear test region,and a confident chronology is established in each sediment peak.With the situation of abnormal distribution of ~(210)Pb,part decline segment method is used in calculation of sedimentation rate,the sedimentation rate using part segment method is mainly in coincidence with the sedimentation rate using ~(137)Cs method.It can get the sedimentation rate of the catchments and the age of sedi- ment layer by using of both ~(137)Cs method and ~(210)Pb method. |
