To investigate the effect of benthic organisms on migration and conversion of phosphorus, our research carried out a quarterly monitoring at two fixed sample points in Lake Taihu, between October 2017 and April 2018. The main contents of the monitoring were the changes of phosphorus in the sediments, overlying water, interstitial water and microorganism in sediments. Microbial content is characterized by using FDA hydrolase analysis. The SMT sequential extraction method was applied in morphometry of phosphorus contained in surface sediment samples in two different trophic level regions of northeast of Lake Taihu. The sum of all forms of phosphorus, which including NH4Cl-P, Fe-P, Al-P, Org-P, Ca-P, and Res-P is regarded as total phosphorus. Through analysis all of them, we can obtain the migration and conversion of phosphorus in sediments in different seasons. Through the determination and analysis of microbial content and bioavailable phosphorus which including WSP, RDP, AAP, Olsen-P, the effect of microorganisms on migration and conversion of phosphorus can be drawn. Then we can explore the role of benthos in it. Recent Publications 1. Li D P and Huang Y (2010) Sedimentary phosphorus fractions and bioavailability as influenced by repeated sediment resuspension.
