Abstract In order to investigate the effects of cascade reservoirs on the temporal and spatial distributions of nitrogen forms along rivers, the sediment samples along Lancang River and Nu River were collected and analyzed during dry and flood seasons, respectively. The sedimentary nitrogen forms, including ion-exchangeable nitrogen (IEF-N), weak-acid leachable nitrogen (WAEF-N), strong alkaline extractable nitrogen (SAEF-N), and strong oxidant extractable nitrogen (SOEF-N), were measured with fractional continuous leaching separation method. The results showed that the content of transformable nitrogen (TTN) in free-flowing reaches of these two rivers was slightly lower than that in the reservoirs, ranging from 512.2 to 1548.5mg/L, and the distribution patterns of four types of transformable nitrogen were basically the same in the same season, following the order of SOEF-N > WAEF-N > SAEF-N > IEF-N in the dry season, and their content ranges were 486.6~1424.8, 3.3~83. 1,1.4~88.8 and 1.2~10.7mg/kg, respectively; but the order changed to WAEF-N > SOEF-N > SAEF-N > IEF-N in flood season, and the content ranges were 360.7~755.7, 42.8~656.2, 6.8~394.3 and 35.8~153.6mg/kg, respectively. And the cascade reservoirs operation might inhibit the release of WAEF-N due to the enrichment of organic matter and the reduction of particle size. As SOEF-N was mainly contained in fine particles, the sediments with smaller grain sizes might inhibit the mineralization of sediments and result in an accumulation of organic nitrogen. Due to the accumulation of organic matter in reservoirs, the content of IEF-N increased gradually. Moreover, in the free-flowing reaches, the surface sediments were basically in oxidation state, and SAEF-N was easier to release from the sediments; while in the reservoirs where the sediments were in weak reduction or reduction state, the SAEF-N was contained and accumulated in sediments.
