| 摘 要： | 生物硅指来源于硅藻、放射虫和海绵骨针等的生源无定形硅.生物硅积累的时空变动被看作是古生产力和古气候重建的一个重要标志.在内湾水域,生物硅可作为初级生产力和营养盐变动状况的良好指标.我们通过文献查阅和对比实验建立一套针对内湾沉积物样品的生物硅测定方法,并应用该方法分析了厦门西海域沉积物样品中的生物硅含量,同时讨论了利用生物硅数据推断此海域的各种环境参数的变动情况的可行性.

| Abstract: | Biogenic Silica (BSi) is mainly produced by diatom,radiolarian,and sponge.Spatial and temporal variations of BSi accumulation have been regarded as important proxys of paleoproductivity and paleoclimate reconstructions.It can also be a good index of primary productivity and nutrient status in inner bay surface waters.In this paper,we developed an appropriate method,to determine the BSi in the sediment samples of Xiamen Western Waters,and demonstrate how to use these BSi content data and their vertical fluctuation curve and horizontal distribution to deduce the surface productivity and evolvement of environment parameters in this area. |
