主　　题：sediment environmental capacity Daya Bay 137Cs 

摘      要：Sediment environmental capacity of pollutants is very important for marine environmental *** on the methodology of a study on water,soil environmental capacity,and mass conservation theory in a system,the concept and model on sediment environmental capacity for 137Cs in Daya Bay were *** static capacity for 137Cs in the upper sediment near the shore at a shallow area was calculated,and the annual dynamic capacity and total dynamic capacity were also calculated through determination of the typical biomass in the *** results showed that the estimated environmental capacity for 137Cs in sedi-ments was approximately equal to the current input of 137Cs into the *** the input of 137Cs in the sedi-ments within the environmental capacity guarantees the sus-tainability of the current situation of the Daya Bay ecosystem and avoidance of a significant degradation of the system.
