Abstract
The species composition and quantitative features of the periphytic algae communities from April, 1993 to June,1997 in Dianshan Lake were reported.The periphytic algae found on submerged macrophytea consisted of 39 species belonging to 37 genera. Among them,there were 13 species and 13 genera of Bacillariphyta, 13 species and 12 genera of Chlorophyta and 7 species and 6 genera of Cyanophyta. The average density and biomass of periphytic algae communities reached their maximum in winter and the minimum in summer,and declined from Hydrilla verticillata>Ceratophyllum demersum>Plastic flagging>Potamogeto crispus>Vallisneria asiatica,P. malaianus. Periphytic algae could have an adverse effect on the growth rate of its macrophyte host and more important shading agents than phytoplankton.
