东海沿岸海底沉积物中的137Cs、210Pb分布及其沉积环境解释
137 Cs and\ 210 Pb profiles of the seabed cores along the East China Sea coast and their implications to sedimentary environment
【摘要】 通过对东海沿岸不同海区８个沉积柱样的１３７Ｃｓ或２１０Ｐｂ剖面的观测，运用１３７Ｃｓ时标法和２１０Ｐｂ过剩法估算了近几十年来的平均沉积速率。并对１３７Ｃｓ的区域分布与蓄积程度及其环境意义进行了初步探讨
【Abstract】 core samples were collected from the different coastal areas of the East China Sea and then their\ 137 Cs or\ 210 Pb profiles were measured separately in the lab By\ 137 Cs time marks and the excess\ 210 Pb methods, the recent sedimentation of the typical coastal geomorphologic units were studied In addition, the regional distribution of the\ 137 Cs activity and the integral flux of the cores , and its implication to the coastal environment were also analyzed
