【摘要】 根据厦门港20个站位沉积物岩心过剩²¹⁰Pb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。更多还原

【Abstract】 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.更多还原
