摘要

Abstract

Based on a new idea for research on cycling of marine biogenic elements

this study showed that only the leachable form phosphorus in natural grain sizes marine sediments constitutes the transferable phosphorous in the sediments. The transferable phosphorus content in the natural grain sizes surface sediments in the Huanghe River estuary adjacent waters ranges from 58.5–69.8 μg/g

accounting for only 9.1%–11.0% of the total phosphorus content

whereas the leachable form (“transferable”) phosphorus content in the sediment after it was totally ground into powder was found to be 454.8–529.2 μg/g

accounting for 73.4%–89.1% of the total phosphorus. Analysis of the correlation between the biomass of benthos and the leachable form (“transferable”) phosphorus showed that most of the leachable form (“transferable”) phosphorus in the totally ground sediment did not participate in the marine biogeochemical cycling. Furthermore

a synchronous survey on benthos showed that the biomass of meio-and macro-benthos exhibited good positive correlation with the leachable form of phosphorus in the natural grain sizes sediment

but poorer correlation with the leachable form (“transferable”) phosphorus in the totally ground sediment

indicating that transferable phosphorus in marine sediment is the leachable form of phosphorus in the natural grain sizes sediments

and is not the previously known leachable form (“transferable”) phosphorus obtained from the totally ground sediment.
