Abstract: In this paper, I discussed the species composition and dynamics of aquatic macrophytes in the Zhushun Lake based upon results of 10 years observations. I also analyzed the replacement of construction species and its affecting factors. It appears that lake siltation is the key factor responsible for the succession of aquatic macrophyte communities. Coverage, density, frequency and importance value were used to describe the quantitative characteristics of the community. The dominant and subdominant species at different stages of the succession were classified based on importance values. The stratification of the communities was determined by using the life-form spectrum of the community. The biomass models of the above and under-water strata were established. The results show that the disappearing rate of species accelerates as the accumulation rate of lake sediments increases. It also demonstrates that the transparency of water only affects the distribution of the submerged plants, and the orthophosphorus concentration of the water is one of the factors limiting the productivity of aquatic macrophyte communities.
