英文摘要Modified Hedley fraction method was used to study the forms and profile distribution in the tidal river network region subjected to rapid deposition and hydrologic disturbance in the Yellow River Delta (YRD) estuary, eastern China. The results showed that the total P (P-t) ranged from 612.1 to 657.8 mg kg(-1). Dilute HCl extractable inorganic P (P-i) was the predominant form in all profiles, both as absolute values and as a percentage of total extracted Pi. The NaOH extractable organic P (P-o) was the predominant form of total extracted P-o, while Bicarb-P-i and C.HCl-P-o were the lowest fractions of total extracted P-i and P-o in all the P forms. The Resin-P concentrations were high in the top soil layer and decreased with depth. The Pearson correlation matrix indicated that Resin-P, Bicarb-P-i, NaOH-P-i, and C.HCl-P-i were strongly positively correlated with salinity, TOC, Ca, Al, and Fe but negatively correlated with pH. The significant correlation of any studied form of organic P (Bicarb-P-o, NaOH-P-o, and C.HCl-P-o) with geochemical properties were not observed in the study. Duncan multiple-range test indicated that the P forms and distribution heterogeneity in the profiles could be attributed to the influences of vegetation cover and hydrologic disturbance.
