Phosphorus release and affecting factors in the sediments of eutrophic water

Abstract

Abstract: In this paper, chemical forms, release rules and their affecting factors of phosphorus in the sediments of eutrophic water were discussed. There are 7 forms including P_sol,P_Al,P_Fe,P_Ca,deoxidized soluble P,P_o-p and P_org . Anaerobic, higher pH or lower pH value, higher temperature, mixing, bioturbation, higher Pconcentration gradient and calcareous sediments composition conditions would improve the release of phosphorus.

Key words: Crop simulation model, Application in regional scale, Remote sensing technique
