摘要: The concentration and distribution characteristics of nitrogen in the sediment interstitial water from Poyang Lake were determined. Diffusive fluxes between overlying estimated. results showed that average total nitrate surface 1.29 0.76 mg/L. Total existed mainly form nitrogen, which amounted to 45.38–73.54 % nitrogen. spatial are similar, contents do not show significant variation at all sampling sites. profiles characterized by sharp gradients near sediment–water interface. increased with degree depth first then decreased depth. concentrations much higher than most sites, indicating tended release water. diffusive interface 0.87 0.86 mg/m2 day, respectively.
