摘      要：The effects of sediment aluminum(Al),organic carbon(OC),and dissolved oxygen(DO)on phosphorus(P)transformation,at the water-sediment interface of a eutrophic constructed lake,were investigated via a series of simulative *** above three factors had various influences on dissolved P concentration,water pH,water and surface sediment appearance,and P *** of Al had the greatest effect on suppressing P release,and the water p H remained alkaline in the water-sediment system under various OC and DO *** dissolution of the added Al was detected.31P-N M R characterization suggested that OC addition did not promote biological P uptake to polyphosphates under oxic *** simulation result on the added phytate indicated the absence of phytate in the original lake *** compared to the reported natural lakes and wetland,the water-sediment system of the constructed lake responded differently to some simulative *** Al,OC,and DO can be controlled with engineering methods,the results of this study provide insights for the practical site restorations.
