In order to explore the distribution characteristics of nitrogen and phosphorus elements in sediments and itspotential of resourceutilization，20 sampling points of sediment at HasuhaiLake，Inner mogolia wereanalyzed.The resultsshowed that totalnitrogen，availablenitrogen，total phosphorus and available phosphorus in the surface sediments were 0.15～ 2.14g/kg，49.01～ 177.14mg/kg，0.30～ 0.45g/kg，and 11.91～ 23.53mg/kg，respectively，the spatial distributioncharacteristics and change trend of these indicators were different.In terms of vertical distribution，the total nitrogen andavailable nitrogen content decreased with the increase of sedimentdepth，which was related to the significant increase ofnitrogen input into the lake in recent years.However，there was no significant change in the vertical distribution of totalphosphorus and availablephosphorus，indicating that there was no significant increase in the amount of phosphorus importedfrom outsidesources.Comparing with otherlakes，it can be confirmed that the sediment of Hasuhai Lake has great potentialfor resource utilization and has certain value as agriculturalresources.
