Abstract Based on three-dimensional fluorescence spectroscopy and ultraviolet visible spectroscopy, the composition, source and structural characteristics of dissolved organic matter (DOM) in the overlying water of Tongzhou area of Beiyun River in flood and non-flood season were compared and analyzed, and the relationship between the content of N and P in the overlying water and the composition of DOM was established, The results indicated that the DOM content in the overlying water of Tongzhou area ranged from 9.17mg/L to 27.78mg/L, showing a general trend of non-flood season > flood season, upstream > downstream. The temporal and spatial characteristics of DOM content were significantly different. The molecular weight of DOM in flood season was smaller than that in non-flood season, and the aromatic degree of DOM in flood season was lower than that in non-flood season; the value of DOM A₂₅₃/A₂₀₃ in flood season was higher than that in non-flood season. DOM in flood season was affected by both land-based humus and biological sources, while that in non-flood season was mainly affected by microbial activities. The concentrations of protein and humus in flood season were significantly lower than those in non-flood season. Protein components accounted for more in non-flood season, while humus components accounted for more in flood season. The maximum fluorescence intensity of C1, C3 and C4 in DOM could indirectly reflect the potential risk of eutrophication in Beiyun River.

Key words： flood and non-flood season DOM beiyun river overlying water fluorescent components
