In this study, sediment internal phosphorus (P) and its supply ability were studied in the algal-dominated zone of Lake Taihu during overwintering recruitment period algae. The results indicated that P fluxes, mobile fractions, kinetics showed dynamic changes from overwinter to algal period. flux concentration diffusive gradient thin film (DGT)-measured labile increased winter summer. However, highest was found spring sediments, as by ratios DGT-P porewater P, suggesting sediments can more for growth Laboratory incubation experiments show with a higher content could release soluble under suitable conditions, thereby increasing chlorophyll (Chla) concentration. algae appeared be correlated concentrations nitrogen than solid-phase Pearson correlation analysis. This study strengthens our understanding relationship between availability sediments.
