Regarding the large amount of dredged sediment produced by Baiyangdian dredging project，we study the resource utilization of greening planting soil prepared by improved dredged sediment. We design three auxiliary material schemes and use membrane covered aerobic fermentation to analyze the changes of physical and chemical indexes of sediment during the test according to the standard of CJ/T340—2016 greening planting soil. The results show that the contents of organic matter and nutrient elements of auxiliary materials directly affect the fermentation effect of sediment. The mixed fermentation effect of farmland waste as the main auxiliary material and sediment is the best. The soil infiltration rate，rapidly available nitrogen，available phosphorus and rapidly available potassium of sediment increase by 44.3%，18.0%，22.8% and 10.0% respectively，which is conducive to the improvement effect of river and lake sediment. This study provides scientific and technological support for large-scale resource disposal of dredged sediment，and realizes the closure of environmental protection dredging industry chain.
