%X Using the methods of sampling in winter and the dividing soil layers in soil profiles, the characteristics of TN, NH4(+)-N and NO3(-)-N concentration distribution in peat sediments of river bed-flood land and valley depression land in Sanjiang Plain where is the most extensive freshwater marsh wetland in China were systematically studied. The results showed that NH4(+)-N and NO3(-)-N was obviously accumulated in Asc layer, and TN content in Hil layer was the highest with the comparing to other layers. TN content in peat sediments was obviously increased with the peat particular size decreasing, NH4(+)-N was mainly distributed in peat component with 0.149-0.074 mm size, and the most of NO3(-)-N was in peat component with 0.03-0.149 mm granule size.
