Abstract对沉积物柱样1,2的137Cs和210Pb定年分析,这两个样品137Cs最大蓄积峰值出现的年份分别为1963年和1986年。利用沉积物中137Cs蓄积峰,计算沉积物的深度沉积速率分别为0.153 1 cm·a-1、0.153 8 cm·a-1,计算出的质量堆积速率分别为0.048 4 g·a-1·cm-2、0.048 2 g·a-1·cm-2。210Pb计算出的两个柱样的沉积速率分别为0.052 0 g·a-1·cm-2,0.051 4 g·a-1·cm-2,137Cs和210Pb计算出的沉积速率,结果较为一致。由此可见,利用137Cs和210Pb综合定年,相互印证,可以消除一些偶然因素带来的...
