摘要: Submerged macrophyte composition and biomass, as well as bioavailable phosphorus in surface water and sediment were studied in 14 temperate lakes in southwestern China. Correlation analysis indicated that macrophyte biomass and species declined with the increase of soluble reactive phosphorus (SRP) in surface water. Sediment bioavailable phosphorus (BAP) and total phosphorus (TP) in investigated lakes changed along, trophic gradient, and the sediment BAP concentration tended to decrease with the increase of macrophytes biomass and species. The correlation analysis between surface water SRP and sediment BAP with macrophytes indicates that the bioavailable phosphorus in water and sediment is coupled with the macrophytes biomass and species. Based on the study, it was suggested that increasing surface water SRP and sediment BAP could cause submerged macrophytes disappearing or decreasing in shallow lake ecosystem. Consequently, the restoration practice for submerged vegetation will favor to succeed when surface water SRP is below 5 mu g/L and sediment BAP is below 60 mu g/g.
