| 英文摘要 | The 103-surface sediment samples collected from the Bohai Sea were extracted by 0.1 mol/LHCl and 1%Na_2CO_3 sequentially for the analysis of biogenic silica. The results showed that biogenic silica contents were in the range of 7.3~54.7 g/kg, with an average of 31.5 g/kg. The measured contents of the biogenic silica were higher than other reported values in the same study area. This might be the result of different extraction methods that were employed in the studies, the extraction by 0.1 mol/L HCl may dissolve the oxides plaque coated on the biogenic silica in the sediment and therefore increase the release of the biogenic silica. Spatial distributions of the biogenic silica were characterized using geographic information system(GIS)and the spatial heterogeneity of the biogenic silica was observed in the surface sediments of the Bohai Sea. The highest content located along the coastal marine of Hebei province, in contrast to the lowest content located in the Laizhou Bay. This suggested long-term terrestrial input of nutrient substances and frequent disturbance by the input of the Yellow River sediments may govern the abundance and distribution of biogenic silica in this area. Principal component analysis indicated the contents of biogenic silica had a significantly(P < 0.01)positive correlation with the contents of clay, fine sand, total organic nitrogen, and organic carbon in the sediment of the Bohai Sea, which further confirmed the effects of grain size and nutrient substance on the accumulation of biogenic silica in the sediment. |
