摘要

Abstract

Dissolved nutrient concentration in the Huanghe (Yellow) River at Lijin was monitored during a water-sediment regulation period and a subsequent rainstorm from 14 June to 19 July

2005. This study provides detailed information on nutrient concentrations in the Huanghe River during the water-sediment regulation and rainstorm periods

and is of significance for the downstream area of the Huanghe River and the Bohai Sea. The average concentrations of nitrate

nitrite and ammonia were 304.7 μmol/L

0.19 μmol/L

and 1.10 μmol/L

respectively

while the average concentrations of dissolved inorganic phosphorus (DIP) and dissolved silicate (DSi) were 0.23 μmol/L and 122.9 μmol/L

respectively. Nutrient concentrations during the water-sediment regulation period were mainly influenced by the dilution effect

floodplain effect and sediment resuspension while dilution and erosion effects were the main factors during the rainstorm. The fluxes of dissolved inorganic nitrogen (DIN)

DIP and DSi during the water-sediment regulation and rainstorm periods accounted for 20.4%

19.5%

16.7% and 4.97%

6.45%

5.47% of the annual nutrient fluxes

respectively. Discharge was the main factor influencing the fluxes of nutrients during both the water-sediment regulation and the rainstorm periods.
