Abstract:To understand the effect of the submerged macrophyte Potamogeton malaianus on the sedimentary phosphorus (P) fraction in Lake Taihu, China, various forms of P in P. malaianus vegetated and non-vegetated areas were quantified with the standard measurement and test (SMT) approach in surface sediments (0~40cm) from the northeast (Gonghu bay) and the south lake regions. Results showed that in Gonghu bay, Fe/Al-P in P. malaianus vegetated areas were significantly higher (P<0.05) in comparison with the non-vegetated areas. However in the south lake, Fe/Al-P in the vegetated areas were significantly lower (P<0.05) in comparison with the non-vegetated areas. OP in the vegetated areas were greatly decreased in comparison with the non-vegetated area in the south lake (P<0.05). The effect of P. malaianus on the sedimentary Ca-P in Gonghu bay and the south lake was within 0~15cm. It is concluded that the submerged macrophyte P. malaianus has an clear effect on the retention of P nutrients.
