The sedimentation rates were estimated on the basis of vertical distribution of excess 210Pb in the sediment cores collected at 20 stations in the Xiamen Harbour,Fujian.The results showed that the sedimentation of the west Xiamen Harbour has speeded up since the Gaoqi-Jimei,Xinglin,Maluam and Yuandang Dams were built.The sedimentation rates ranged from 0.5 to 7.8cm/a,with faster sedimentation occurring near Baozhu Isle and to the south of the Hou Isle as well as at Song Isle-Gulang Isle Passage.The sedimentation rates in the outer Xiamen Harbour were 0.2-5.4cm/a.There were different level of siltation within the main channel of the Xiamen Harbour.The causes of sedimentation are looked at and propositions of preventing siltation are presented.

根据厦门港20个站位沉积物岩心过剩~(210)Pb的垂直分布估算了沉积速率。结果表明,自从高崎~集美、杏林、马銮和员当诸海堤修建以来厦门西港的沉积加快了。其沉积速率范围为 0.5~7.8cm/a,其中宝珠屿附近海区、猴屿南部海区和嵩(屿)~鼓(浪屿)水道有较快的淤积。厦门外港的淤积速率范围为0.2~5.4cm/a,且有从九龙江口外港逐渐增加的趋势。厦门港主航道虽然存在着不同程度的淤积,但只有局部海区淤积较快。本文还讨论了厦门港淤积的原因,并提出了某些防淤建议。

Distributions of 210Pb, 228Th, and the fallout nuclides 239,240Pu and 3H in sedime-tn core from Bosten Lake have been measured. The sedimentation rates based on 210Pb, 228Th, and 239,210pu are 0.31 cm/yr, 0.26 cm/yr and 0.33 cm/yr, respectively. According to 210Pb measurements, the sedimentation rates remain invariable during recent 100 yrs. The sediments of this lake have preserved the historical record of atmospheric nuclear test. 239'240Pu maximum distribution appears in 1963 ± 2, which fits very well with...

Distributions of 210Pb, 228Th, and the fallout nuclides 239,240Pu and 3H in sedime-tn core from Bosten Lake have been measured. The sedimentation rates based on 210Pb, 228Th, and 239,210pu are 0.31 cm/yr, 0.26 cm/yr and 0.33 cm/yr, respectively. According to 210Pb measurements, the sedimentation rates remain invariable during recent 100 yrs. The sediments of this lake have preserved the historical record of atmospheric nuclear test. 239'240Pu maximum distribution appears in 1963 ± 2, which fits very well with the peak period of nuclear testing during the 1960's. 3H maximum in pore water appears in 1969 as a result of lake water mixing which made it delayed.

作者测定了博斯腾湖沉积岩心~(210)Pb、~(228)Th和核试验释放核素~(239,240)Pu、~3H的分布,并据~(210)Pb、~(228)Th、~(239,240)Pu的结果估算湖泊的沉积速率,分别为0.31cm/a,0.26cm/a和0.33cm/a。它表明该湖泊近百年来沉积环境十分稳定。沉积物岩心极好地保存了人类大气核试验的历史记录。~(239,240)Pu分布在1963±2出现峰值,与60年代核试验高峰期相当吻合。沉积物孔隙水~3H分布的峰值出现在1969年,与湖水的混合过程有关。
