| Abstract: | Wudalianchi,the group of freshwater lakes in Northeast China were surveyed regarding phosphorus fractions in the surface sediments.A sequential extraction procedure was adopted to investigate Ca2-P,Ca8-P,Ca10-P,Al-P,Fe-P and O-P;amount of different P species and correlation among the P species were studied.Results showed the range of TP concentrations in the surface sediments and revealed that content of Fe-P was the highest,accounting for 34.73%～56.57%;the order of magnitude in terms of contents of different P species was identified.As to phosphorus activation coefficient(PCA),it was showed in all the sediment samples that TP was easily transformed into Olsen-P,which implied the great potential for bio-available phosphorus.It was also found that Fe-P and Al-P had much more influence on TP amount in sediments and Ca2-P that was more active than other species was positively correlated with Fe-P,Al-P and TP. |
