Abstract：The spatial distribution characteristics and correlations of different nitrogen species in the overlying water, interstitial water and sediment in north of Taihu (Zhushan Bay,Meiliang Bay and Gonghu Bay) have been investigated, meanwhile the diffusion fluxes of NH4+-N have been counted. The spatial characteristic showed that the average concentrations distribution trends of NH4+-N were Zhushan Bay>Meiliang Bay>Gonghu Bay in the overlying water, interstitial water and sediment; the distribution trends of NO3--N were Gonghu Bay>Meiliang Bay>Zhushan Bay in the overlying water and sediment, but Meiliang Bay>Gonghu Bay>Zhushan Bay in interstitial water; TN have the similar distribution trends with NH4+-N in the overlying water, interstitial water and sediment. In Zhushan Bay,Meiliang Bay and Gonghu Bay, the average diffusion fluxes of NH4+-N were 1009.27μmol/(m2·d), 49.35μmol/(m2·d) and 3.14μmol/(m2·d) separately. Significant correlations of NH4+-N was found between overlying water, interstitial water and the surface sediment.
