| Abstract: | The contents of different phosphorus forms in surface sediments and the soils of water-level-fluctuating zone of the backwater reach of Pengxi River,a tributary of the Three Gorges Reservoir(TGR) in China,were studied using the standard measurement and test(SMT) procedure of phosphorus forms in freshwater sediments.Correlation coefficients between phosphorus forms and sample geochemical characteristics were analyzed.The results indicated that the total phosphorus(TP) content in the soils of water-level-fluc... |
